This is the run that is discussed in the GENETIS paper submitted to Physical Review D in December of 2021. It was conducted beginning on March 19, 2021. The preprint can be found here. It ran for 31 generations with 50 individuals per generation. Each individual was run through AraSim for 300,000 neutrinos.

The ratio of generative operators was: 72% crossover, 22% immigration, 6% reproduction. 

The ratio of selection operators was: 80% roulette, 20% tournament, 0% rank.

The highest scoring individual had a fitness score of 5.24. However, when it was rerun with many more neutrinos (3*10^7), it had a score of 4.90, an 11% improvement over the ARA bicone.

This run was conducted before the introduction of the automatic run_details.txt generator. Instead, there is a file called Run_Notes.txt (attached) which details some of the errors that were encountered. These errors were remedied during runs by removing the offending AraOut file (which had too high of a fitness score due to a weight being calculated to be greater than 1, which shouldn't be possible) and have since been prevented by modifying the data file AraSim uses to calculate the weights.

//Notes for AraSim_Polarity_Fix_2020_03_19 run

3/27/21: We ran into a rare error we see where AraSim gives an absurd weight (>>1) to a passed event. We reverted the state and replaced the effective volume in that file (AraOut_6_3_8.txt) with the average from the other AraOut files for that individual. DO NOT USE AraOut_6_3_8.txt WHEN ANALYZING ARASIM DATA.

5/9/21: We ran into the same error as above. We reverted the state and replaced the effective volume in the file (AraOut_23_7_7.txt). DO NOT USE AraOut_23_7_7.txt WHEN ANALYZING ARASIM DATA.

5/11/21: We ran into the same error. We are reverting the state and replacing the file (AraOut_25_10_6.txt). DO NOT USE AraOut_25_10_6.txt WHEN ANALYZING ARASIM DATA.
