A few (!) updates remain to be shared

Indeed, Chesstroid is full of comments reporting tons of updates which makes it a source of fresh information. This contribution of the visitors brings a dynamic ambiance which hides my slowness in sharing things in time. So, thanks to everyone for covering me!

Anyways, i'll be back again soon to complete the saga, in line with chronological order of the releases.

Simplification: do razoring only for depth 1

The razoring heuristic is quite a drastic pruning technique,
using a depth 0 search at internal nodes of the search tree
to estimate the true value of depth n nodes. This patch limits
this razoring to the case of internal nodes of depth 1.
Author: Jarrod Torriero (DU-jdto)

LLR: 2.95 (-2.94,2.94) [-3.00,1.00]
Total: 8043 W: 1865 L: 1716 D: 4462

LLR: 2.95 (-2.94,2.94) [-3.00,1.00]
Total: 32890 W: 5577 L: 5476 D: 21837

Opportunities opened by this patch: it would be interesting to
know if it brings Elo to re-introduce razoring or soft razoring
at depth >= 2, maybe using a larger margin to compensate for the
increased pruning effect.

Impressive sir!

Unknown said...

If cfish and sometimes armfish are better than stockfish why dont they do stockfish in C etc?

chysiddh14 said...
