Can we do this, run GP with certain settings, with check pointing enabled, and stop, change settings and start run from the check point. Reason for doing this is to see indirectly the impact of "dynamic" changes. If initially in expolration phase the parsimony pressure is low (none), and as with time/generation need to add more Parsimony pressure for bloat control etc one way i thought was to use check point and freeze of the states.
Let me know if this sounds reasonable.
