| AySz88 2008-01-26 14:51:33 | I've been noticing some awfully similar results on the stats lists. For example, right now, PhaseRotEb1a has four users with best results of 3.353723, and five with 3.353306. Both I and [SETI.USA]zeitgeistmovie.com are topping Linac88MHz900MeV1 with 0.226396 while everyone else is negative (and I know I didn't inject any manual designs). Are these truly results which have almost exactly the same number of correct-energy muons? Or are we generating the same designs from the best-100 lists somehow? |
| Stephen Brooks 2008-01-27 21:00:55 | The scoring counts particles, so if two similar designs let exactly the same set of particles through, they will have identical scores. |
| AySz88 2008-01-31 07:09:13 | Hmm - I was under the impression that some parts of the simulation were random (like decay time of a pion to a muon), such that this would be very unlikely. Was it changed, or am I just imagining things?  |
| Stephen Brooks 2008-01-31 10:18:29 | The randomness was made deterministic in version 4.44 I think. That means for the same seed, the particles should decay in exactly the same way (it took quite a while to get this working right). |
