how to plot a figure that y-axes is fitness function and x-axes is generation number of ga and the fitness value are increasing at each generation in matlab

To plot a figure with the y-axis as the fitness function and the x-axis as the generation number in MATLAB, you can follow these steps:

1. Generate the fitness values for each generation of your genetic algorithm (GA) implementation.
2. Create a vector or array to store the fitness values for each generation.
3. Use the plot function to plot the fitness values against the generation numbers.

Here's an example code snippet:

main.m
% Generate fitness values for each generation
fitnessValues = [0.5, 0.7, 0.9, 1.2, 1.6]; % Example fitness values, replace with your own

% Create a vector for the generation numbers
generationNumbers = 1:length(fitnessValues);

% Plot the fitness values against the generation numbers
plot(generationNumbers, fitnessValues)

% Add axis labels and a title
xlabel('Generation Number')
ylabel('Fitness Function')
title('Fitness Function vs Generation Number')

14 lines

Ensure that you have the fitness values for each generation stored in the fitnessValues variable. Also, adjust the axis labels and the plot title as per your requirements.

This code will plot a figure where the y-axis represents the fitness function and the x-axis represents the generation number. The plot will show how the fitness values increase across different generations.

Remember to replace the fitnessValues variable with the actual fitness values generated by your GA implementation.

Hope this helps!
