Creates populations bigger or smaller than set in config

Open havietisov opened this issue 2 years ago • 2 comments

when initial_connection value in the config set to fs_neat_hidden, partial_direct, full_direct, and and num_hidden is other than zero, creates population of size, different from what is set in config, on windows version specifically

To Reproduce Steps to reproduce the behavior:

  1. Set population count to, lets say, 200
  2. set num_hidden to 2
  3. run for a while
  4. you will eventually witness populations getting bigger or smaller than 200

Expected behavior Population to be exactly of a size set in config

Screenshots I hope log would be enough
