scaling the fitness scores in matlab

To scale fitness scores in MATLAB, you can use the rescale function. This function rescales the values in a given array or matrix between a specified range.

Here is the syntax for using the rescale function:

main.m
normalized_scores = rescale(fitness_scores, new_min, new_max);
63 chars
2 lines

• fitness_scores is the array or matrix containing the original fitness scores.
• new_min is the desired minimum value for the rescaled scores.
• new_max is the desired maximum value for the rescaled scores.

For example, if you have fitness scores ranging from 0 to 100 and you want to rescale them between 0 and 1, you can use the following code:

main.m
fitness_scores = [85, 92, 78, 97, 80];
rescaled_scores = rescale(fitness_scores, 0, 1);
88 chars
3 lines

This will return the rescaled scores as:

main.m
0.5556    0.7778    0.3333    1.0000    0.4444
47 chars
2 lines

Now, the fitness scores are scaled between 0 and 1, making them suitable for further analysis or visualization.

Note that the rescale function requires MATLAB R2019a or later.

Hope this helps!
