Wiggling to stability may be a target we simply can't hit any more. Attached is a log of one very long wiggle in newchapter. The score stabilizes at about 30 iterations (7 minutes on my machine), and a loop that tests for changes of >= 1 pt would give up there, but after 90 iterations it suddenly gains 47 more points. It gradually adds about 50 more points, then stabilizes again sometime after 112 iterations. Then after 432 iterations (18 minutes) it suddenly adds 40 more points. I gave up logging after 33 minutes, when it was still slowly gaining fractions.
Okay, now I really want wiggle sliders back. Maybe we can shortcut some of that by increasing wiggle accuracy over time.
Having a fairly powerful computer (4.1ghz proc), I decided to test just how long this wiggle will actually run before hitting stability. I used the CASP refinement puzzle.
Iterations 1-8700 (0:00-85:00) (roughly 600 points)
Starting from a score of 9177, it wiggled up to my old high score of 9650 within 200 iterations, acting very much like current Foldit's wiggle. After this, it started displaying the behavior mentioned below
As mentioned before, wiggle will appear to freeze for a good 100-200 iterations, after which it would jump up between 10-15 points in 2-5 iterations, then will crawl for the next 100ish iterations, gaining 5-10 points very steadily, then this process will repeat. Most of the point gains came from jumps. Jumps happened every 100-300 iterations. Final jump before 8700 was 14 points
Iterations 8700-12500 (85:00-113:00) (roughly 75 points)
At this point, the behavior is very similar, though most of the point gains came from crawling, with only 1-3 points per 100 iterations during crawl. The jumps also started happening less often, every 300-500 iterations, and only gained 2-4 points per jump, no jumps over 4 points.
Iterations 12500-14500 (113:00-)
I had stopped watching during this block, and only gained 5-10 points during this whole time. When I brought the client back up at iteration 14500 it had stopped moving. I let it run until iteration 16720 (161:00), and since there had been no gains for over 2000 iterations, I stopped it.
Results: around 2 hours of wiggle, and 678 points later, I now have a protein sitting at 9855.
We are trying a "Wiggle Power" option to give some control over runtime and stability. See the feedback http://fold.it/portal/node/996664 for more info.
Here are some wiggle number I did last night on 663:
