Run T-0236 passed

2026-11-06 · Evidence: SPRT Sequential probability ratio test. Games are played until the accumulated evidence reaches one of two bounds or the game limit fixed in advance; then the test stops.

Hypothesis

Combining pawn-history value learning, delaying root-suffix sorting until exceeding the initial search depth, reducing non-cutoff deep TT Transposition table: a cache of already searched positions, keyed by a hash of the position. entries by one ply, penalizing failed quiet killers and countermoves even on tactical best moves, exempting quiet king evasions in check at cut-nodes from history pruning, and capping LMR for later quiet siblings after a refuted full re-search yields at least neutral overall strength against the baseline, with potential superadditive gains.

Stages

Point estimate with the reported 95-percent half-width, per stage. The dashed line is zero. Estimates from a stopped sequential test are biased by the stopping rule; the interval is nominal.

Playing strength: AFE

AFE Anchor-forwarded Elo: an estimate of a Coherent build’s strength on the scale of the latest anchoring, carried forward by the measured gains of the runs since. An estimate, not a measurement. Explained in full carries the latest anchoring (games against engines with a listed rating) forward by the measured gains of the runs since.

Measured: long stage against the predecessor +2.76 ± 2.30 Elo (SPRT-stopped: the test ended as soon as it reached its bound).

AFE 3683 [3670; 3695] nominal 90 % model interval

An estimate, not a measurement. Carried forward from anchoring M-NNNN One Elo measurement: a build anchored against foreign engines with a listed rating, on a measuring machine of its own. Numbered in the order delivered; the register run it measured is named with it. The series continues the entries E-0001 to E-0012 and starts at M-0013.
