For decades, some of humankind's greatest minds have been fascinated with the concept of an early game T4. Does it really exist or is it an unattainable achievement, destined to forever lie just beyond our grasp?
Recently, lengthy XG2 4-ply rollouts have been done for 43D-33 and 41S-54 at the four main scores (money, dmp, save, go). David Rockwell and Dmitriy's rollouts of 43D-33-d (combining to [C B2] "^108) appear to prove that 43D-33 is not quite a T4. For 41S-54, money is the holdout score, and it seems that S is slightly weaker than X, though David is currently hyperextending Neil/Dmitriy's rollout in the hopes of a reversal.
Over the years, many rollouts have been done for 63S-32, not always with the same play emerging on top. With many close candidates, there is a reasonable chance that a different play might be best at each of the four scores.
We seek rollateers for 63S-32 (see diagram below). Bot is XG2, and settings are 4-ply checker play, and 4-ply (or higher) cube. You may roll out whatever candidate plays you want as many trials as you like, but here are suggested parameters:
- money: SWZU (46k), $ (20k), H (5k) -- six plays
dmp: ...WS$ (31k), Z (10k), U% (5k) -- six plays
save: ...ZS (31k), UH (20k), $TW (5k) -- seven plays
go: ......S$WH% (31k), Z (10k) -- six plays
The four scores above can be activated with the U, D, S and G buttons, respectively, on the XG2 menu under the board.
Plays: S = Split (24/21 13/11), Z = reverse split (24/22 13/10), W = Wild (24/21 6/4), U = Up (24/22 24/21), $ = Slot (13/10 6/4), % = alt slot (13/11 8/5), H = Hit (6/1*), T = sTack/Tower (13/8).
Number of trials: 5k = 5184, 10k = 10368, 20k = 20736, 31k = 31104, 46k = 46656.
To avoid duplicate work, please post here under this thread when you have started your rollout. When you have finished, e-mail me the rollout to nack2000@sbcglobal.net in case we want to extend it. (You may also post the result here: optional.)
Thanks in advance for your participation!
