Additionally, what would be the solution for your specific problem? 
Based on the table below, you can select an appropriate type of decision variables to use.

</div>

Let's go through a basic and advanced example.


### Simple Benchmark Function

**Using Problem dict**

```python
from mealpy import FloatVar, SMA
import numpy as np

def objective_function(solution):
    return np.sum(solution**2)

problem = {
    "obj_func": objective_function,
    "bounds": FloatVar(lb=(-100., )*30, ub=(100., )*30),
    "minmax": "min",
    "log_to": None,
}

## Run the algorithm
model = SMA.OriginalSMA(epoch=100, pop_size=50, pr=0.03)
g_best = model.solve(problem)
print(f"Best solution: {g_best.solution}, Best fitness: {g_best.target.fitness}")
```

**Define a custom Problem class**


**Please note that, there is no more `generate_position`, `amend_solution`, and `fitness_function` in Problem class.**
We take care everything under the DataType Class above. Just choose which one fit for your problem.
**We recommend you define a custom class that inherit `Problem` class if your decision variable is not FloatVar**


```python
from mealpy import Problem, FloatVar, BBO 
import numpy as np

# Our custom problem class
class Squared(Problem):
    def __init__(self, bounds=None, minmax="min", data=None, **kwargs):
        self.data = data 
        super().__init__(bounds, minmax, **kwargs)

    def obj_func(self, solution):
        x = self.decode_solution(solution)["my_var"]
        return np.sum(x ** 2)

## Now, we define an algorithm, and pass an instance of our *Squared* class as the problem argument. 
bound = FloatVar(lb=(-10., )*20, ub=(10., )*20, name="my_var")
problem = Squared(bounds=bound, minmax="min", name="Squared", data="Amazing")
model = BBO.OriginalBBO(epoch=100, pop_size=20)
g_best = model.solve(problem)
```


### Set Seed for Optimizer (So many people asking for this feature)

You can set random seed number for each run of single optimizer.

```python
model = SMA.OriginalSMA(epoch=100, pop_size=50, pr=0.03)
g_best = model.solve(problem=problem, seed=10)  # Default seed=None
```


### Large-Scale Optimization

```python
from mealpy import FloatVar, SHADE
import numpy as np

def objective_function(solution):
    return np.sum(solution**2)

problem = {
    "obj_func": objective_function,
    "bounds": FloatVar(lb=(-1000., )*10000, ub=(1000.,)*10000),     # 10000 dimensions
    "minmax": "min",
    "log_to": "console",
}

## Run the algorithm
optimizer = SHADE.OriginalSHADE(epoch=10000, pop_size=100)
g_best = optimizer.solve(problem)
print(f"Best solution: {g_best.solution}, Best fitness: {g_best.target.fitness}")
```



### Distributed Optimization / Parallelization Optimization

Please read the article titled [MEALPY: An open-source library for latest meta-heuristic algorithms in Python](https://doi.org/10.1016/j.sysarc.2023.102871) to 
gain a clear understanding of the concept of parallelization (distributed 
optimization) in metaheuristics. Not all metaheuristics can be run in parallel.


```python
from mealpy import FloatVar, SMA
import numpy as np


def objective_function(solution):
    return np.sum(solution**2)

problem = {
    "obj_func": objective_function,
    "bounds": FloatVar(lb=(-100., )*100, ub=(100., )*100),
    "minmax": "min",
    "log_to": "console",
}

## Run distributed SMA algorithm using 10 threads
optimizer = SMA.OriginalSMA(epoch=10000, pop_size=100, pr=0.03)
optimizer.solve(problem, mode="thread", n_workers=10)        # Distributed to 10 threads
print(f"Best solution: {optimizer.g_best.solution}, Best fitness: {optimizer.g_best.target.fitness}")

## Run distributed SMA algorithm using 8 CPUs (cores)
optimizer.solve(problem, mode="process", n_workers=8)        # Distributed to 8 cores
print(f"Best solution: {optimizer.g_best.solution}, Best fitness: {optimizer.g_best.target.fitness}")
```



## The Benefit Of Using Custom Problem Class (BEST PRACTICE)

### Optimize Machine Learning model

In this example, we use SMA optimize to optimize the hyper-parameters of SVC model.

```python
from sklearn.svm import SVC
from sklearn.model_selection import train_test_split
from sklearn.preprocessing import StandardScaler
from sklearn import datasets, metrics

from mealpy import FloatVar, StringVar, IntegerVar, BoolVar, MixedSetVar, SMA, Problem


# Load the data set; In this example, the breast cancer dataset is loaded.
X, y = datasets.load_breast_cancer(return_X_y=True)

# Create training and test split
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.3, random_state=1, stratify=y)

sc = StandardScaler()
X_train_std = sc.fit_transform(X_train)
X_test_std = sc.transform(X_test)

data = {
    "X_train": X_train_std,
    "X_test": X_test_std,
    "y_train": y_train,
    "y_test": y_test
}


class SvmOptimizedProblem(Problem):
    def __init__(self, bounds=None, minmax="max", data=None, **kwargs):
        self.data = data
        super().__init__(bounds, minmax, **kwargs)

    def obj_func(self, x):
        x_decoded = self.decode_solution(x)
        C_paras, kernel_paras = x_decoded["C_paras"], x_decoded["kernel_paras"]
        degree, gamma, probability = x_decoded["degree_paras"], x_decoded["gamma_paras"], x_decoded["probability_paras"]

        svc = SVC(C=C_paras, kernel=kernel_paras, degree=degree, 
                  gamma=gamma, probability=probability, random_state=1)
        # Fit the model
        svc.fit(self.data["X_train"], self.data["y_train"])
        # Make the predictions
        y_predict = svc.predict(self.data["X_test"])
        # Measure the performance
        return metrics.accuracy_score(self.data["y_test"], y_predict)

my_bounds = [
    FloatVar(lb=0.01, ub=1000., name="C_paras"),
    StringVar(valid_sets=('linear', 'poly', 'rbf', 'sigmoid'), name="kernel_paras"),
    IntegerVar(lb=1, ub=5, name="degree_paras"),
    MixedSetVar(valid_sets=('scale', 'auto', 0.01, 0.05, 0.1, 0.5, 1.0), name="gamma_paras"),
    BoolVar(n_vars=1, name="probability_paras"),
]
problem = SvmOptimizedProblem(bounds=my_bounds, minmax="max", data=data)
model = SMA.OriginalSMA(epoch=100, pop_size=20)
model.solve(problem)

print(f"Best agent: {model.g_best}")
print(f"Best solution: {model.g_best.solution}")
print(f"Best accuracy: {model.g_best.target.fitness}")
print(f"Best parameters: {model.problem.decode_solution(model.g_best.solution)}")
```



### Solving Combinatorial Problems


**Traveling Salesman Problem (TSP)**

In the context of the Mealpy for the Traveling Salesman Problem (TSP), a solution is a possible route that 
represents a tour of visiting all the cities exactly once and returning to the starting city. The solution is 
typically represented as a permutation of the cities, where each city appears exactly once in the permutation.


For example, let's consider a TSP instance with 5 cities labeled as A, B, C, D, and E. A possible solution could be 
represented as the permutation `[A, B, D, E, C]`, which indicates the order in which the cities are visited. This 
solution suggests that the tour starts at city A, then moves to city B, then D, E, and finally C before returning to city A.


```python
import numpy as np
from mealpy import PermutationVar, WOA, Problem

# Define the positions of the cities
city_positions = np.array([[60, 200], [180, 200], [80, 180], [140, 180], [20, 160],
                           [100, 160], [200, 160], [140, 140], [40, 120], [100, 120],
                           [180, 100], [60, 80], [120, 80], [180, 60], [20, 40],
                           [100, 40], [200, 40], [20, 20], [60, 20], [160, 20]])
num_cities = len(city_positions)
data = {
    "city_positions": city_positions,
    "num_cities": num_cities,
}

class TspProblem(Problem):
    def __init__(self, bounds=None, minmax="min", data=None, **kwargs):
        self.data = data
        super().__init__(bounds, minmax, **kwargs)

    @staticmethod
    def calculate_distance(city_a, city_b):
        # Calculate Euclidean distance between two cities
        return np.linalg.norm(city_a - city_b)

    @staticmethod
    def calculate_total_distance(route, city_positions):
        # Calculate total distance of a route
        total_distance = 0
        num_cities = len(route)
        for idx in range(num_cities):
            current_city = route[idx]
            next_city = route[(idx + 1) % num_cities]  # Wrap around to the first city
            total_distance += TspProblem.calculate_distance(city_positions[current_city], city_positions[next_city])
        return total_distance

    def obj_func(self, x):
        x_decoded = self.decode_solution(x)
        route = x_decoded["per_var"]
        fitness = self.calculate_total_distance(route, self.data["city_positions"])
        return fitness


bounds = PermutationVar(valid_set=list(range(0, num_cities)), name="per_var")
problem = TspProblem(bounds=bounds, minmax="min", data=data)

model = WOA.OriginalWOA(epoch=100, pop_size=20)
model.solve(problem)

print(f"Best agent: {model.g_best}")                    # Encoded solution
print(f"Best solution: {model.g_best.solution}")        # Encoded solution
print(f"Best fitness: {model.g_best.target.fitness}")
print(f"Best real scheduling: {model.problem.decode_solution(model.g_best.solution)}")      # Decoded (Real) solution
```



**Job Shop Scheduling Problem Using Woa Optimizer**

Note that this implementation assumes that the job times and machine times are provided as 2D lists, where 
`job_times[i][j]` represents the processing time of job `i` on machine `j`.

Keep in mind that this is a simplified implementation, and you may need to modify it according to the specific 
 requirements and constraints of your Job Shop Scheduling problem.


```python
import numpy as np
from mealpy import PermutationVar, WOA, Problem


job_times = [[2, 1, 3], [4, 2, 1], [3, 3, 2]]
machine_times = [[3, 2, 1], [1, 4, 2], [2, 3, 2]]

n_jobs = len(job_times)
n_machines = len(machine_times)

data = {
    "job_times": job_times,
    "machine_times": machine_times,
    "n_jobs": n_jobs,
    "n_machines": n_machines
}

class JobShopProblem(Problem):
    def __init__(self, bounds=None, minmax="min", data=None, **kwargs):
        self.data = data
        super().__init__(bounds, minmax, **kwargs)

    def obj_func(self, x):
        x_decoded = self.decode_solution(x)
        x = x_decoded["per_var"]
        makespan = np.zeros((self.data["n_jobs"], self.data["n_machines"]))
        for gene in x:
            job_idx = gene // self.data["n_machines"]
            machine_idx = gene % self.data["n_machines"]
            if job_idx == 0 and machine_idx == 0:
                makespan[job_idx][machine_idx] = job_times[job_idx][machine_idx]
            elif job_idx == 0:
                makespan[job_idx][machine_idx] = makespan[job_idx][machine_idx - 1] + job_times[job_idx][machine_idx]
            elif machine_idx == 0:
                makespan[job_idx][machine_idx] = makespan[job_idx - 1][machine_idx] + job_times[job_idx][machine_idx]
            else:
                makespan[job_idx][machine_idx] = max(makespan[job_idx][machine_idx - 1], makespan[job_idx - 1][machine_idx]) + job_times[job_idx][machine_idx]
        return np.max(makespan)


bounds = PermutationVar(valid_set=list(range(0, n_jobs*n_machines)), name="per_var")
problem = JobShopProblem(bounds=bounds, minmax="min", data=data)

model = WOA.OriginalWOA(epoch=100, pop_size=20)
model.solve(problem)

print(f"Best agent: {model.g_best}")                    # Encoded solution
print(f"Best solution: {model.g_best.solution}")        # Encoded solution
print(f"Best fitness: {model.g_best.target.fitness}")
print(f"Best real scheduling: {model.problem.decode_solution(model.g_best.solution)}")      # Decoded (Real) solution
```



**Shortest Path Problem**

In this example, the graph is represented as a NumPy array where each element represents the cost or distance between two nodes.

Note that this implementation assumes that the graph is represented by a symmetric matrix, where `graph[i,j]` 
represents the distance between nodes `i` and `j`. If your graph representation is different, you may need to modify 
the code accordingly.

Please keep in mind that this implementation is a basic example and may not be optimized for large-scale problems. 
Further modifications and optimizations may be required depending on your specific use case.


```python
import numpy as np
from mealpy import PermutationVar, WOA, Problem

# Define the graph representation
graph = np.array([
    [0, 2, 4, 0, 7, 9],
    [2, 0, 1, 4, 2, 8],
    [4, 1, 0, 1, 3, 0],
    [6, 4, 5, 0, 3, 2],
    [0, 2, 3, 3, 0, 2],
    [9, 0, 4, 2, 2, 0]
])


class ShortestPathProblem(Problem):
    def __init__(self, bounds=None, minmax="min", data=None, **kwargs):

**Location Optimization**


Let's consider an example of location optimization in the context of a retail company that wants to open a certain 
number of new stores in a region to maximize market coverage while minimizing operational costs.

A company wants to open five new stores in a region with several potential locations. The objective is to 
determine the optimal locations for these stores while considering factors such as population density and 
transportation costs. The goal is to maximize market coverage by locating stores in areas with high demand while 
minimizing the overall transportation costs required to serve customers.

By applying location optimization techniques, the retail company can make informed decisions about where to open new 
stores, considering factors such as population density and transportation costs. This approach allows the company to 
maximize market coverage, make efficient use of resources, and ultimately improve customer service and profitability.

Note that this example is a simplified illustration, and in real-world scenarios, location optimization problems can 
involve more complex constraints, additional factors, and larger datasets. However, the general process remains 
similar, involving data analysis, mathematical modeling, and optimization techniques to determine the optimal 
locations for facilities.


```python
import numpy as np
from mealpy import BinaryVar, WOA, Problem

# Define the coordinates of potential store locations
locations = np.array([
    [2, 4],
    [5, 6],
    [9, 3],
    [7, 8],
    [1, 10],
    [3, 2],
    [5, 5],
    [8, 2],
    [7, 6],
    [1, 9]
])
# Define the transportation costs matrix based on the Euclidean distance between locations
distance_matrix = np.linalg.norm(locations[:, np.newaxis] - locations, axis=2)

# Define the number of stores to open
num_stores = 5

# Define the maximum distance a customer should travel to reach a store
max_distance = 10

data = {
    "num_stores": num_stores,
    "max_distance": max_distance,
    "penalty": 1e10
}


class LocationOptProblem(Problem):
    def __init__(self, bounds=None, minmax=None, data=None, **kwargs):
        self.data = data
        self.eps = 1e10
        super().__init__(bounds, minmax, **kwargs)

    # Define the fitness evaluation function
    def obj_func(self, x):
        x_decoded = self.decode_solution(x)
        x = x_decoded["placement_var"]
        total_coverage = np.sum(x)
        total_dist = np.sum(x[:, np.newaxis] * distance_matrix)
        if total_dist == 0:                 # Penalize solutions with fewer stores
            return self.eps
        if total_coverage < self.data["num_stores"]:    # Penalize solutions with fewer stores
            return self.eps
        return total_dist


bounds = BinaryVar(n_vars=len(locations), name="placement_var")
problem = LocationOptProblem(bounds=bounds, minmax="min", data=data)

model = WOA.OriginalWOA(epoch=50, pop_size=20)
model.solve(problem)

print(f"Best agent: {model.g_best}")                    # Encoded solution
print(f"Best solution: {model.g_best.solution}")        # Encoded solution

```


**Supply Chain Optimization**

Let's assume we have a supply chain network with 5 distribution centers (DC1, DC2, DC3, DC4, DC5) and 10 products 
(P1, P2, P3, ..., P10). Our goal is to determine the optimal allocation of products to the distribution centers in 
a way that minimizes the total transportation cost.

Each solution represents an allocation of products to distribution centers. We can use a binary matrix with 
dimensions `(10, 5)` where each element `(i, j)` represents whether product `i` is allocated to distribution center `j`. 
For example, a chromosome `[1, 0, 1, 0, 1]` would mean that product `1` is allocated to `DC1`, `DC3`, `DC5`.

We can add the maximum capacity of each distribution center, therefor we need penalty term to the fitness 
evaluation function to penalize solutions that violate this constraint. The penalty can be based on the degree of 
violation or a fixed penalty value.


```python
import numpy as np
from mealpy import BinaryVar, WOA, Problem

# Define the problem parameters
num_products = 10
num_distribution_centers = 5

# Define the transportation cost matrix (randomly generated for the example)
transportation_cost = np.random.randint(1, 10, size=(num_products, num_distribution_centers))

data = {
    "num_products": num_products,
    "num_distribution_centers": num_distribution_centers,
    "transportation_cost": transportation_cost,
    "max_capacity": 4,      # Maximum capacity of each distribution center
    "penalty": 1e10         # Define a penalty value for maximum capacity of each distribution center
}


class SupplyChainProblem(Problem):
    def __init__(self, bounds=None, minmax=None, data=None, **kwargs):
        self.data = data
        super().__init__(bounds, minmax, **kwargs)

    def obj_func(self, x):
        x_decoded = self.decode_solution(x)
        x = x_decoded["placement_var"].reshape((self.data["num_products"], self.data["num_distribution_centers"]))

        if np.any(np.all(x==0, axis=1)):    
        # If any row has all 0 value, it indicates that this product is not allocated to any distribution center.
            return 0

        total_cost = np.sum(self.data["transportation_cost"] * x)
        # Penalty for violating maximum capacity constraint
        excess_capacity = np.maximum(np.sum(x, axis=0) - self.data["max_capacity"], 0)
        penalty = np.sum(excess_capacity)
        # Calculate fitness value as the inverse of the total cost plus the penalty
        fitness = 1 / (total_cost + penalty)
        return fitness


bounds = BinaryVar(n_vars=num_products * num_distribution_centers, name="placement_var")
problem = SupplyChainProblem(bounds=bounds, minmax="max", data=data)

model = WOA.OriginalWOA(epoch=50, pop_size=20)
model.solve(problem)

print(f"Best agent: {model.g_best}")                    # Encoded solution
print(f"Best solution: {model.g_best.solution}")        # Encoded solution
print(f"Best fitness: {model.g_best.target.fitness}")
print(f"Best real scheduling: {model.problem.decode_solution(model.g_best.solution)['placement_var'].reshape((num_products, num_distribution_centers))}")
```


**Healthcare Workflow Optimization Problem**

Define a chromosome representation that encodes the allocation of resources and patient flow in the emergency 
department. This could be a binary matrix where each row represents a patient and each column represents a resource 
(room). If the element is 1, it means the patient is assigned to that particular room, and if the element is 0, it 
means the patient is not assigned to that room

Please note that this implementation is a basic template and may require further customization based on the specific 
objectives, constraints, and evaluation criteria of your healthcare workflow optimization problem. You'll need to 
define the specific fitness function and optimization objectives based on the factors you want to optimize, such as 
patient waiting times, resource utilization, and other relevant metrics in the healthcare workflow context.


```python
import numpy as np
from mealpy import BinaryVar, WOA, Problem

# Define the problem parameters
num_patients = 50  # Number of patients
num_resources = 10  # Number of resources (room)

# Define the patient waiting time matrix (randomly generated for the example)
# Why? May be, doctors need time to prepare tools,...
waiting_matrix = np.random.randint(1, 10, size=(num_patients, num_resources))

data = {
    "num_patients": num_patients,
    "num_resources": num_resources,
    "waiting_matrix": waiting_matrix,

    "penalty_value": 1e2,         # Define a penalty value
    "penalty_patient": 1e10
}

        # If a patient a assigned to more than 3 room, not allow
        if np.any(np.all(x==0, axis=1)) or np.any(np.sum(x>3, axis=1)):
            return self.data["penalty_patient"]

        # Calculate the fitness value based on the objectives
        resource_utilization_fitness = 1 - np.mean(room_used) / self.data["max_resource_capacity"]

        return fitness

**Production Optimization Problem**

Let's consider a simplified example of production optimization in the context of a manufacturing company that 
produces electronic devices, such as smartphones. The objective is to maximize production output while minimizing 
production costs.

This example uses binary representations for production configurations, assuming each task can be assigned to a 
resource (1) or not (0). You may need to adapt the representation and operators to suit your specific production 
optimization problem.


```python

# Define the problem parameters
num_tasks = 10
num_resources = 5

# Example task processing times
task_processing_times = np.array([2, 3, 4, 2, 3, 2, 3, 4, 2, 3])

# Example resource capacity
resource_capacity = np.array([10, 8, 6, 12, 15])

# Example production costs and outputs
production_costs = np.array([5, 6, 4, 7, 8, 9, 5, 6, 7, 8])
production_outputs = np.array([20, 18, 16, 22, 25, 24, 20, 18, 19, 21])

# Example maximum total production time

# Example maximum defect rate

# Penalty for invalid solution
penalty = -1000

    "production_costs": production_costs,
    "production_outputs": production_outputs,
    "max_defect_rate": max_defect_rate,
    "penalty": penalty
}

**Employee Rostering Problem Using Woa Optimizer**

The goal is to create an optimal schedule that assigns employees to shifts while satisfying various 
constraints and objectives. Note that this implementation assumes that shift_requirements array 
has dimensions (num_employees, num_shifts), and shift_costs is a 1D array of length num_shifts.

Please keep in mind that this is a simplified implementation, and you may need to modify it according to the 
specific requirements and constraints of your employee rostering problem. Additionally, you might want to 
introduce additional mechanisms or constraints such as fairness, employee preferences, or shift 
dependencies to enhance the model's effectiveness in real-world scenarios.

For example, if you have 5 employees and 3 shifts, a chromosome could be represented as [2, 1, 0, 2, 0], 
where employee 0 is assigned to shift 2, employee 1 is assigned to shift 1, 
employee 2 is assigned to shift 0, and so on.

```python
import numpy as np
from mealpy import IntegerVar, WOA, Problem


shift_requirements = np.array([[2, 1, 3], [4, 2, 1], [3, 3, 2]])
shift_costs = np.array([10, 8, 12])

num_employees = shift_requirements.shape[0]
num_shifts = shift_requirements.shape[1]

data = {
    "shift_requirements": shift_requirements,
    "shift_costs": shift_costs,
    "num_employees": num_employees,
    "num_shifts": num_shifts
}

    def __init__(self, bounds=None, minmax="min", data=None, **kwargs):
        self.data = data
        super().__init__(bounds, minmax, **kwargs)

    def obj_func(self, x):
        x_decoded = self.decode_solution(x)
        x = x_decoded["shift_var"]

        shifts_covered = np.zeros(self.data["num_shifts"])
        total_cost = 0
        for idx in range(self.data["num_employees"]):
            shift_idx = x[idx]
            shifts_covered[shift_idx] += 1
            total_cost += self.data["shift_costs"][shift_idx]
        coverage_diff = self.data["shift_requirements"] - shifts_covered
        coverage_penalty = np.sum(np.abs(coverage_diff))
        return total_cost + coverage_penalty


bounds = IntegerVar(lb=[0, ]*num_employees, ub=[num_shifts-1, ]*num_employees, name="shift_var")
problem = EmployeeRosteringProblem(bounds=bounds, minmax="min", data=data)

print(f"Best real scheduling: {model.problem.decode_solution(model.g_best.solution)}")      # Decoded (Real) solution
```

**Maintenance Scheduling**

In maintenance scheduling, the goal is to optimize the schedule for performing maintenance tasks on
various assets or equipment. The objective is to minimize downtime and maximize the utilization of
assets while considering various constraints such as resource availability, task dependencies, and time constraints.

Each element in the solution represents whether a task is assigned to an asset (1) or not (0). The schedule 
specifies when each task should start and which asset it is assigned to, aiming to minimize the total downtime.

By using the Mealpy, you can find an efficient maintenance schedule that minimizes downtime,
maximizes asset utilization, and satisfies various constraints, ultimately optimizing 
the maintenance operations for improved reliability and productivity.

```python

import numpy as np
from mealpy import BinaryVar, WOA, Problem


num_tasks = 10
num_assets = 5
task_durations = np.random.randint(1, 10, size=(num_tasks, num_assets))

data = {
    "num_tasks": num_tasks,
    "num_assets": num_assets,
    "task_durations": task_durations,
    "unassigned_penalty": -100         # Define a penalty value for no task is assigned to asset
}


class MaintenanceSchedulingProblem(Problem):
    def __init__(self, bounds=None, minmax=None, data=None, **kwargs):
        self.data = data
        super().__init__(bounds, minmax, **kwargs)

    def obj_func(self, x):
        x_decoded = self.decode_solution(x)
        x = x_decoded["task_var"]
        downtime = -np.sum(x.reshape((self.data["num_tasks"], self.data["num_assets"])) * self.data["task_durations"])
        if np.sum(x) == 0:
            downtime += self.data["unassigned_penalty"]
        return downtime


bounds = BinaryVar(n_vars=num_tasks * num_assets, name="task_var")
problem = MaintenanceSchedulingProblem(bounds=bounds, minmax="max", data=data)

<details><summary><h3>Custom Problem </h3></summary>


For our custom problem, we can create a class and inherit from the `Problem` class, named the child class the  
'Squared' class. In the initialization method of the 'Squared' class, we have to set the `bounds`, and `minmax`  
of the problem (bounds: a problem's type, and minmax: a string specifying whether the problem is a 'min' or 'max' problem). 

Afterwards, we have to override the abstract method `obj_func()`, which takes a parameter 'solution' (the solution 
to be evaluated) and returns the function value. The resulting code should look something like the code snippet 
below. 'Name' is an additional parameter we want to include in this class, and you can include any other additional 
parameters you need. But remember to set up all additional parameters before super() called.


```python
from mealpy import Problem, FloatVar, BBO 
import numpy as np

# Our custom problem class
class Squared(Problem):
    def __init__(self, bounds=None, minmax="min", data=None, **kwargs):
        self.data = data 
        super().__init__(bounds, minmax, **kwargs)

    def obj_func(self, solution):
        return np.sum(solution ** 2)

    
## Now, we define an algorithm, and pass an instance of our *Squared* class as the problem argument. 
problem = Squared(bounds=FloatVar(lb=(-10., )*20, ub=(10., )*20), minmax="min", name="Squared", data="Amazing")
model = BBO.OriginalBBO(epoch=10, pop_size=50)
g_best = model.solve(problem)

## Show some attributes
print(g_best.solution)
print(g_best.target.fitness)
print(g_best.target.objectives)
print(g_best)
print(model.get_parameters())
print(model.get_name())
print(model.get_attributes()["g_best"])
print(model.problem.get_name())
print(model.problem.n_dims)
print(model.problem.bounds)
print(model.problem.lb)
print(model.problem.ub)
```

<details><summary><h3>Tuner class (GridSearchCV/ParameterSearch, Hyper-parameter tuning)</h3></summary>


We build a dedicated class, Tuner, that can help you tune your algorithm's parameters.

```python
from opfunu.cec_based.cec2017 import F52017
from mealpy import FloatVar, BBO, Tuner

## You can define your own problem, here I took the F5 benchmark function in CEC-2017 as an example.
f1 = F52017(30, f_bias=0)

p1 = {
    "bounds": FloatVar(lb=f1.lb, ub=f1.ub),
    "obj_func": f1.evaluate,
    "minmax": "min",
    "name": "F5",
    "log_to": "console",
}

paras_bbo_grid = {
    "epoch": [10, 20, 30, 40],
    "pop_size": [50, 100, 150],
    "n_elites": [2, 3, 4, 5],
    "p_m": [0.01, 0.02, 0.05]
}

term = {
    "max_epoch": 200,
    "max_time": 20,
    "max_fe": 10000
}

if __name__ == "__main__":
    model = BBO.OriginalBBO()
    tuner = Tuner(model, paras_bbo_grid)
    tuner.execute(problem=p1, termination=term, n_trials=5, n_jobs=4, mode="thread", n_workers=4, verbose=True)
    ## Solve this problem 5 times (n_trials) using 5 processes (n_jobs), each process will handle 1 trial. 
    ## The mode to run the solver is thread (mode), distributed to 4 threads 

    print(tuner.best_row)
    print(tuner.best_score)
    print(tuner.best_params)
    print(type(tuner.best_params))
    print(tuner.best_algorithm)
    
    ## Save results to csv file 
    tuner.export_results(save_path="history", file_name="tuning_best_fit.csv")
    tuner.export_figures()
    
    ## Re-solve the best model on your problem 
    g_best = tuner.resolve(mode="thread", n_workers=4, termination=term)
    print(g_best.solution, g_best.target.fitness)
    print(tuner.algorithm.problem.get_name())
    print(tuner.best_algorithm.get_name())
```

<details><summary><h3>Multitask class (Multitask solver)</h3></summary>


We also build a dedicated class, Multitask, that can help you run several scenarios. For example:

1. Run 1 algorithm with 1 problem, and multiple trials
2. Run 1 algorithm with multiple problems, and multiple trials
3. Run multiple algorithms with 1 problem, and multiple trials
4. Run multiple algorithms with multiple problems, and multiple trials


```python
#### Using multiple algorithm to solve multiple problems with multiple trials

## Import libraries
from opfunu.cec_based.cec2017 import F52017, F102017, F292017
from mealpy import FloatVar
from mealpy import BBO, DE
from mealpy import Multitask

## Define your own problems
f1 = F52017(30, f_bias=0)
f2 = F102017(30, f_bias=0)
f3 = F292017(30, f_bias=0)

p1 = {
    "bounds": FloatVar(lb=f1.lb, ub=f1.ub),
    "obj_func": f1.evaluate,
    "minmax": "min",
    "name": "F5",
    "log_to": "console",
}

p2 = {

    "obj_func": f2.evaluate,
    "minmax": "min",
    "name": "F10",
    "log_to": "console",
}

p3 = {

    "obj_func": f3.evaluate,
    "minmax": "min",
    "name": "F29",
    "log_to": "console",
}

## Define models
model1 = BBO.DevBBO(epoch=10000, pop_size=50)
model2 = BBO.OriginalBBO(epoch=10000, pop_size=50)
model3 = DE.OriginalDE(epoch=10000, pop_size=50)
model4 = DE.SAP_DE(epoch=10000, pop_size=50)

## Define termination if needed
term = {
    "max_fe": 3000
}

## Define and run Multitask
if __name__ == "__main__":
    multitask = Multitask(algorithms=(model1, model2, model3, model4), problems=(p1, p2, p3), terminations=(term, ), modes=("thread", ), n_workers=4)
    # default modes = "single", default termination = epoch (as defined in problem dictionary)
    multitask.execute(n_trials=5, n_jobs=None, save_path="history", save_as="csv", save_convergence=True, verbose=False)
    # multitask.execute(n_trials=5, save_path="history", save_as="csv", save_convergence=True, verbose=False)
    
    ## Check the directory: history/, you will see list of .csv result files
```

## My Comments

* Meta-heuristic Categories: (Based on this article: [link](https://doi.org/10.1016/j.procs.2020.09.075))
    + Evolutionary-based: Idea from Darwin's law of natural selection, evolutionary computing 
    + Swarm-based: Idea from movement, interaction of birds, organization of social ...
    + Physics-based: Idea from physics law such as Newton's law of universal gravitation, black hole, multiverse 
    + Human-based: Idea from human interaction such as queuing search, teaching learning, ... 
    + Biology-based: Idea from biology creature (or microorganism),...
    + System-based: Idea from eco-system, immune-system, network-system, ...
    + Math-based: Idea from mathematical form or mathematical law such as sin-cosin 
    + Music-based: Idea from music instrument

* Difficulty - Difficulty Level (Personal Opinion): **Objective observation from author**. Depend on the number of 
  parameters, number of equations, the original ideas, time spend for coding, source lines of code (SLOC).
    + Easy: A few paras, few equations, SLOC very short
    + Medium: more equations than Easy level, SLOC longer than Easy level
    + Hard: Lots of equations, SLOC longer than Medium level, the paper hard to read.
    + Hard* - Very hard: Lots of equations, SLOC too long, the paper is very hard to read.
    
** For newbie, we recommend to read the paper of algorithms which difficulty is "easy" or "medium" difficulty level.
