get the generation number and pass it to the fitness function PyGAD
I am trying to set up the fitness function in PyGAD but inside this I am calling and external process for each solution(individual) get the resulting data and perform the fitness. So I'll have a folder for each generation and each individual for…

Errors while using PyGAD's parallel processing for neural network training in Google Colab
I'm trying to use a PyGAD to train a Keras sequential model. Currently, it can find a solution just fine but it takes really long to do it.
I'm already using batching for the keras side, but what's killing performance is PyGAD. Just so you can get…

Why does PyGad fitness_function not work when inside of a class?
I am trying to train a genetic algorithm but for some reason it does not work when it's stored inside of a class. I have two equivalent pieces of code but the one stored inside of a class fails. It returns this..
raise ValueError("The fitness…

For a project on a HPC I want to use pygad to produce sets of points that can then be passed to jobs on the cluster:
Therefore, I would like all points within a population to be unique (time on the cluster is expensive so i would like to optimally…
