FEATURE REQUEST: Spatial awareness

1

Hello, I've read that GAs can be improved by introduced a spatial dimension, which can avoid early local minima being found. This effectively means giving each individual an x,y coordinate,...

Hi! Great project, thanks. However I've experianced some bugs. model = pygad.GA(someparameters - may be even sample model from documentation) model.run() model.plot_fitness(plot_type="scatter") ok model.run() model.plot_fitess() ok model.plot_fitness(plot_type="scatter") --------------------------------------------------------------------------- ValueError Traceback...

1

With PyGAD 2.18.0 the `keep_elitism=1` paramter was introduced. Apparently this only works when no crossover operation is selected. This is a strange behavior, because in my understanding Selection(e.g. Elitism) and...

allow_duplicate_genes=False has no effect in 2.17.0

2

Hi, I tested the pygad library version 2.17.0 for solving the knapsack problem and I observed that even if I set allow_duplicate_genes=False, I still have duplicated genes in the solution....
