How chromosome in Genetic Algorithms Toolbox works in detailed

Hello, I need answers about constitution of the chromosomes, their length, coding of chromosome in detail, crossover and mutation process. Generally, how it works in detailed Maybe on example or code please. In GA toolbox documentation does not specify how the GA determines the length of the chromosome and encodes variable??? Thanks Radek

Hi Radek,

I understand that you would like to know the details regarding the chromosomes of the Genetic Algorithm.

The chromosome encoding depends on the solution that we are looking for. It can be a sequence of double values or binary values. Please follow this link to know more about it: https://www.mathworks.com/help/gads/genetic-algorithm-options.html#f14223

If we are choosing a custom chromosome then we also need to create custom crossover and mutation functions.

Genetic Algorithm uses different types of crossovers such as single-point, two-point etc. Please follow this link for more information on the types of crossover functions being used: https://www.mathworks.com/help/gads/genetic-algorithm-options.html#f7820

Similarly it uses various mutation functions like gaussian mutation, uniform mutation etc. Please follow this link for more information on mutation function types used: https://www.mathworks.com/help/gads/genetic-algorithm-options.html#f6633

I hope this helps!

Thank you.
