I am trying to make my AI win the board game "Catan" against my friends. Therefore i am using the python implementation of NEAT.

As I changed the values of weight_mutate_power, response_mutate_power, bias_mutate_power and compatibility_threshold in the config the number of individuals and species exploded (~Doubled every generation and exceeded pop_size).

weight_mutate_power = 12
response_mutate_power = 0
bias_mutate_power = 0.5
compatibility_threshold = 3

Playing with those values I discovered that the rate of the explosion changes in relation to those values (Everything worked fine with standard Values from the documentation).

Any idea how to control this behavior? My cluster is drowning in genomes...
