I am using a non stationary penalty function for solving a constrained
I've implemented a steady state ga with, we say for example,
Nevertheless, as the penalty function changes its value, the individuals
survived from one generation to the subsequent have to be re-evaluated,
while the "new" individuals does not need to be re-evaluated.
Now, my question is the following: is it enough to update the first 30% of
the population after the ga-step is completed?
I think this is not right, because after the ga.step the individuals are
re-ordered on the basis of objective functions that refers to two different
This problem occurs whenever the objective function change with the
generation index (from 0 to the maximum number of generations allowed).
Thanks in advance for any suggestion.
