4.12 died silently after about 12hours last night.
I' restarted it and will have an eye on it.
It's the background-version on WinNT.

bye

New columns appear on the stats table when the results from the different simulations have to be kept separate for some reason or other. v4.00 v4.0x and v4.1x calculate scientifically-different simulations (it so happens that what the v4.0 branches were simulating was not what I wanted to simulate!), but as with the version-3 project I feel that I should still credit these people with the number of units they've crunched on incorrect versions. The rightmost-column only displays the best muon transfer from the _correct_ version of the simulation.
v4.2 will supercede v4.1x, being more accurate, so those figures will be reset to 0.000% again and only v4.2x results used for them. v4.2 will also go in another column by itself. If the table gets too wide for people, I could always merge the first two columns. Or just make the font REALLY WEENY so that nobody can read it.

Everthings ok, all systems working well. When do you think about adding a new coloum to the stats tab?

OK well version 4.12 is released now. Does it work OK for everyone?

I was just thinking we have a lot of computing power here and was trying to imagine how it would all work if I allowed you to vary ALL of the solenoid radii and fields independantly (within engineering tolerances of course).

Things I plan to do by version 4.2 are to decrease the randomness of the results by making the pion decay be simulated more accurately and also include a intermediate-save feature so that simulations-in-progress are not lost. I'm wondering whether it would be worth also completely generalising the genome at this point.

Alternatively I could test out the more-general optimisation on the decay-channel-only _first_, while doing the less-risky enhancements on the version4/bending chicane, so that I can compare it directly with the results of the last decay-channel-only run (v3.11). This would mean the release of a version 3.2 and potentially two optimisation projects running in parallel, which fortunately is managable because the programs already upload to different directories for each version.

This is about a month or so away. Sooner than that I plan to release 4.12 with a bugfix to the genetic algorithm (no more identical parents) and another optimisation elsewhere.
