Thank You for suggestions... Oscilations for mutation rates is more biological. If you look at our own past, there are periods of stable ecosystems that lasts for thousand (milions) of years and then happens some radiation, polution, or natural disaster that causes lots of mutations. Then again is period of stability that enables natural selection of newformed biodiversity. That cycle repeats on and on and will probably repeat again... With short period of 16x mutation rate I get lots of mutations and then with long period of 0.16x mutation rates I get natural selection.
However I gave up of my zerobots, now is new simulation in progress, animal minimalis and alga minimalis. I gradually decrease movement efficiency, right now bang efficiency is around 10%, zero momentum on. I'll post sim when bang efficiency drops to zero
