Gene type

[soheilminer]

Hello everyone,

I'm using this package for my research in stochastic mine planning, and I'm trying to adapt it to my own problem.
I'm just wondering if I can define each gene as a tuple that contains two values, and only perform the crossover/mutation functions on the second value while the first one is fixed. Any help is appreciated.

Hello,

Yes this is possible using the gene_space parameter. This is an example which makes the value of the first gene fixed (1) and the value of the second one is None so that it can be randomly changed using the GA.

ga_instance = pygad.GA(...,
                       gene_space=[[1], None],
                       ...)
