I can't checkga_instance.run_completed == False during runtime becausega_instance.run_completed is initialized toTrue only after a finished run. It was never initialized toFalse inside ofclass GA. This line is missing frompygad.py I suppose (lines 911 - 941):

self.run_completed=False

Workaround for now inexample.py:

ga_instance=pygad.GA(# [...])ga_instance.run_completed=False
