Saving intermediate population during GA

18 views (last 30 days)
I need some help to find out a way to store the information related to every generation of the GA
(both the variable and the fitness values)
It could be both on an external file ( e.g. in a .txt file) or in a struct array.
Which one do you suggest? And how can I do it?
Thanks in advance

You can save whatever you like using an output function. For examples of output functions (using a different syntax, be careful, GA uses its own), see a MATLAB example, and an Optimization Toolbox example.

It seems that the example gives only the values of the variables, I need the corresponding fval for each indiviual, did you get it?

You can use my function
to store all intermediate results in a global variable, and easily inspect them later on.
