Multi Objective Optimization Using Genetic Algorithm in MATLAB are performed by our best team of developers with the aid of the Direct Search Toolbox and Genetic Algorithm, Multi-objective optimization employing genetic algorithms (GA) in MATLAB can be carried out in an efficient manner. We are filled with all the trending ideas and tools so get your work done by our team .For addressing the optimization issues which include diverse objectives, this toolkit offers crucial functions. By using GA, we offer an extensive manual to carry out multi-objective optimization in MATLAB:
Step-by-Step Measures
- Specify the Objective Functions
The objective function which we want to enhance must be specified initially. We would have several objective functions for multi-objective optimization which should be enhanced or diminished in a concurrent manner.
function f = objectiveFunctions(x)
% Define the first objective function
f1 = x(1)^2 + x(2)^2;
% Define the second objective function
f2 = (x(1) – 1)^2 + x(2)^2;
% Combine the objectives into a column vector
f = [f1; f2];
end
- Configure the Genetic Algorithm
In order to configure and address the multi-objective optimization issue, we can make use of the gamultiobj function.
% Define the number of variables
nvars = 2;
% Set the lower and upper bounds for the variables
lb = [-10 -10];
ub = [10 10];
% Call the gamultiobj function
options = optimoptions(‘gamultiobj’, ‘Display’, ‘iter’, ‘PlotFcn’, @gaplotpareto);
[x, fval, exitflag, output, population, scores] = gamultiobj(@objectiveFunctions, nvars, [], [], [], [], lb, ub, options);
% Display the results
disp(‘Solutions:’)
disp(x)
disp(‘Objective function values at the solutions:’)
disp(fval)
- Visualize the Pareto Front
In the objective space, a group of non-dominated findings is determined through the Pareto front.
% Plot the Pareto front
figure;
plot(fval(:,1), fval(:,2), ‘bo’);
xlabel(‘Objective 1’);
ylabel(‘Objective 2’);
title(‘Pareto Front’);
grid on;

end
function f = objectiveFunctions(x)
% Define the first objective function
f1 = x(1)^2 + x(2)^2;
% Define the second objective function
f2 = (x(1) – 1)^2 + x(2)^2;
% Combine the objectives into a column vector
f = [f1; f2];
end
Description of the Code
- Objective Functions: A column vector of objective function values are returned by the objective function which acquires a vector x as input.
- Configure Genetic Algorithm:
- nvars: In the optimization problem, nvars represents the number of variables.
- lb, ub: For the variables, lb and ub are the vectors which specify the lower and upper bounds.
- gamultiobj: By using genetic algorithms, it conducts multi-objective optimization through the MATLAB function gamultiobj. Exhibiting the iteration process and visualizing the Pareto front are involved in this option.
- Plotting:
- Crucial findings are exhibited. To plot the performance consideration among the objectives, Pareto front is visualized here.
Modifying the Genetic Algorithm
We must modify the options to personalize the genetic algorithm in an efficient manner:
- PopulationSize: Considering g specific generation, it regulates the number of persons.
- Generations: The number of generations is regulated here.
- CrossoverFraction: It specifies the population fraction, which is specifically generated by crossover.
- MutationFcn: In an explicit manner, it indicates the mutation function.
- SelectionFcn: Crucially, it signifies the function of selection.
A sample model of customizing options:
‘PopulationSize’, 100, …
‘Generations’, 200, …
‘CrossoverFraction’, 0.8, …
‘MutationFcn’, @mutationadaptfeasible, …
‘SelectionFcn’, @selectiontournament, …
‘Display’, ‘iter’, …
‘PlotFcn’, @gaplotpareto);
