This run was started on 10/23/2020. The purpose was to attempt to demonstrate evolution by beginning from 50 identical individuals in the initial generation (which had previously produced a low score).
This run was the first time we removed the penalty on fitness scores for antennas which exceeded the borehole radius. It was also the first time we increased the number of neutrinos thrown up to 300,000. 50 fully asymmetric individuals were evolved over 25 generations.
There was a 50/50 split for roulette/tournament selection and 75%/10%/15% for crossover/reproduction/immigration. While the evolution was somewhat flat, we do believe we demonstrated evolution because the average score rose as the run evolved.
(Note that the final generation was interrupted but the plot was still made, hence the drop to 0 for all scores on the plot) |
