Hi All,
Since my experience with Framsticks has just begun this could very well be
something I'm doing wrong but I thought I'd ask anyway...
If gene pool capacity =200 then why do the genotypes in the genepool
window keep showing increasing numbers of genotypes, 12000+ for example?
Program grows increasingly sluggish sometimes. Example: simulating 3
creatures at a time on flat land with selection for say vertical position
and pool capacity at 200, after ~25M steps there are 12K+ genotypes in the
gene pool window, the program still runs okay, but if changes are made to
selection, or deletion of some genotypes, or clearing of performance then
the program is likely to become *very* slow to respond to nonresponding.
This is on WinXPhome, P3-1GHz, 512MB. Memory is not the problem, there's
still plenty left open when this happens. Unregistered (for now) version
2.2.
If you decide to tweak the fitness parameters during an experiment, how do
you properly clear out the old fitness values for the current genotypes?
Thanks!!

This is strange, if you have such examples, please send your
settings and bug description to support@framsticks.com

This is due to inherent complexity of this operation.
It sometimes requires n*n computations (where n is the
number of genotypes), and sometimes n*n*n, or even more.

If you change fitness formula, it is done automatically.
If you change environment parameters and would like to forget
about old fitness, click "clear performance" and wait :-)
