Run T-0026 failed
· Evidence: SPRT Sequential probability ratio test. Games are played until the accumulated evidence reaches one of two bounds; then the test stops.
Hypothesis
Verified razoring should strengthen Coherent by replacing full searches of shallow fail-low nodes with cheaper quiescence searches while preserving tactically forcing replies.
Stages
| Field | short stage |
|---|---|
| Verdict | failed |
| Elo Strength difference to the opponent, estimated from the games, with a 95-percent half-width where the oracle reported one. Never an absolute rating. | −11.11 ± 8.42 |
| nElo Normalised Elo: the Elo difference divided by the spread of the game results, so that the SPRT bounds mean the same at different time controls. | −13.45 ± 10.18 |
| Games | 4,474 |
| Wins / draws / losses | 1,583 / 1,165 / 1,726 |
| pentanomial Games are played in pairs with swapped colours; the five counts are the pairs scoring 0, ½, 1, 1½ and 2 points. | 303 / 451 / 811 / 430 / 242 |
| LLR Log-likelihood ratio, the running evidence of an SPRT. It starts at 0; a stage passes at the upper bound (about +2.94) and fails at the lower one (about −2.94). | −2.95 |
| Bounds | −2.94 … +2.94 |
| SPRT Sequential probability ratio test. Games are played until the accumulated evidence reaches one of two bounds; then the test stops. | [0.0, 5.0] |
| Error rates α / β | 0.05 / 0.05 |
| Model | normalized |
| time control Base time plus increment per move in seconds, e.g. 8+0.08: eight seconds per game plus 0.08 seconds per move. | 8+0.08 |
| Book | A |
