Instance: Genetic Algorithm for Function Optimization

Enhancing the Rastrigin function is assumed in this instance. In optimization, this function is examined as a general criterion.

f(x)=10n+∑i=1n[xi2−10cos⁡(2πxi)]f(x) = 10n + \sum_{i=1}^{n} [x_i^2 – 10\cos(2\pi x_i)]f(x)=10n+∑i=1n[xi2−10cos(2πxi)], in which the number of dimensions is denoted as nnn (for easiness, consider n=2n = 2n=2).

Stepwise Implementation in MATLAB

Step 1: Specify the Objective Function

A function file rastrigin.m has to be developed:

function y = rastrigin(x)

y = 10 * numel(x) + sum(x .^ 2 – 10 * cos(2 * pi * x));

end

Step 2: Initialize Genetic Algorithm Parameters

options = optimoptions(‘ga’, …

‘PopulationSize’, 100, …        % Population size

‘MaxGenerations’, 200, …        % Maximum number of generations

‘CrossoverFraction’, 0.8, …     % Crossover fraction

‘MutationFcn’, @mutationadaptfeasible, … % Mutation function

‘Display’, ‘iter’);               % Display iteration info

Step 3: Execute the Genetic Algorithm

nvars = 2; % Number of variables (dimensions)

lb = -5.12 * ones(1, nvars); % Lower bound

ub = 5.12 * ones(1, nvars);  % Upper bound

[x, fval] = ga(@rastrigin, nvars, [], [], [], [], lb, ub, [], options);

% Display results

fprintf(‘Optimal Solution: x = [%.4f, %.4f]\n’, x(1), x(2));

fprintf(‘Objective Function Value: %.4f\n’, fval);

Sample Dataset Optimization: Wine Quality Dataset

From the UCI Machine Learning Repository, we intend to employ the Wine Quality Dataset. To forecast wine quality, our project focuses on enhancing a regression model.

% Separate features and target variable

X = table2array(data(:, 1:end-1)); % Features

y = table2array(data(:, end));     % Target variable

Step 2: Describe the Objective Function for Model Training

In order to assess the performance of a regression model (for instance: linear regression), the cross-validation will be utilized by the objective function.

A function file wineObjective.m must be developed:

function mse = wineObjective(params)

% Define model parameters

lambda = params(1); % Regularization parameter

% Cross-validation

k = 5;

cv = cvpartition(size(X, 1), ‘KFold’, k);

mseVals = zeros(k, 1);

for i = 1:k

% Split data

X_train = X(training(cv, i), :);

y_train = y(training(cv, i), :);

X_test = X(test(cv, i), :);

y_test = y(test(cv, i), :);

% Train model

model = fitrlinear(X_train, y_train, ‘Lambda’, lambda);

% Predict

y_pred = predict(model, X_test);

% Compute mean squared error

mseVals(i) = mean((y_test – y_pred) .^ 2);

end

% Average MSE across folds

mse = mean(mseVals);

end

Step 3: Initialize Genetic Algorithm Parameters

options = optimoptions(‘ga’, …

‘PopulationSize’, 50, …

‘MaxGenerations’, 100, …

‘CrossoverFraction’, 0.8, …

‘Display’, ‘iter’);

lb = [0]; % Lower bound for lambda

ub = [10]; % Upper bound for lambda

nvars = 1; % Number of variables (lambda)

Step 4: Execute the Genetic Algorithm

% Optimize

[x, fval] = ga(@wineObjective, nvars, [], [], [], [], lb, ub, [], options);

% Display results

fprintf(‘Optimal Solution: Lambda = %.4f\n’, x);

fprintf(‘Objective Function Value (MSE): %.4f\n’, fval);
