Optimization via GA eventually ends itself
Optimization via GA eventually ends itself

Correct me if I'm wrong but should GA optimization last forever or until a user aborts it manually?
cAlgo often ends optimization by itself when it's obvious there are still better solutions out there.
Why?

Do you have an ETA on our ability to influence those parameters? I was really hoping I could use your platform for some complex parameter optimization but it just doesn't cut it.
"25 iterations were done"
I would very much like this to be editable to infinity.
"best fitness value was not improved during last 5 iterations"
This can indicate that an optimal solution is close at hand or that the fitness criteria were poor. Either way it doesn't seem like a good idea for that condition to stop the process.
And please ensure that you are using a cryptographically secure pRNG for the mutation function(s) (they don't have patterns and are as robust as a standard computer can get).
