Alex M Worked with Alex P on fixing a new issue that appeared in AraSim. We were getting effective volumes of 0 in generation 4, despite getting nonzero fitness scores in previous generations. We made a fix that seems to give *some* non-zero effective volumes. The sequence of zero and non-zero fitness scores appears to correspond exactly with the length of the cones, but oddly it's preferring the shorter ones so I'm skeptical.  I'm going to continue this run for another generation to see if generation 4 was a fluke, but because the change we made was substantial, we need to perform another run since previous generations may have been affected by this bug.
Alex P Worked a little bit to fix error with graphs submitting, worked with Alex M on fixing some problems and submitted long job of the ARA actual bicone so that we can get a worthy vEff from that change the graphing software to include it automatically rather than generating a new one each run. Started with just 100,000 neutrinos but hope to do a million but wanted to do 100,000 to see how long it takes before running something that large. Found XFintoARA error with Alex too that could've caused new 0 vEff error. Over the weekend check on the 100,000 neutrino run and possibly run a 1,000,000 run, but also continue to run our full runs over the weekend, possible focusing on getting our 9 generation database run up to 13 or more gens.
Leo Finished work on the 2 chromosome method. We fixed the issues with the roulette algorithm so that we get a second generation that we expect. Next week, Eliot and I hope to start looking, at and working with XF to see where we will need to make adjustments.
