How can I load previously saved workspace and continue the optimization from where it was left off with the same configurations of population size and mutation generation on jEPLUS+EA?

edit

Sometimes in an optimization process, my computer stops and I have to restart the process on jEPLUS+EA. Every time I try to load previously saved workspace and continue the optimization from where it was left off, the configuration of population size and max generations is modified to 10 and 200, respectively. I already tried to modify the ea.cfg file, altering the population size and max generations to 50 and 100, respectively, but this still has happened. Any suggestion? Thanks!
