Re: A complete 2000 lines of code engine

Minic is finally getting >1000 at STS @10sec per position (single core, on quite old hardware) : 1051 :) still not very smart but that's better.

Re: Faster testing ?

Ok I get your point but i'd be curious to see some stats on the subject (match lenght, tpye of draws...). Sudden-death matches can also suffer from blunder in end game or failure to find a mate sequence being too short on time and living on a small increment... I guess I shall work on sudden death +...

Re: Faster testing ?

Is there some interest in faster testing (ultra-bullet style)? something that would be like a CCRL 40/1 scale (meaning 4 times faster than CCRL 40/4, so around 20sec or 15sec on recent hardware). It would be quite cheap testing and a database can be built pretty quickly. This is already pretty good...

Re: Texel tuning Zurichess quiet like generator

Another related question would be, what it you're best error on quiet-labeled from zurichess ?

Minic best is 0.0574 (with K=1.47037), but I read somewhere that Zurichess itself goes down to 0.056.

Tried now with 20% of CCRL data (around 7mil positions):

k: 0.6089, Error: 0.09379 Residual: 0.30625 STC Tests: Cancelled early +38 =46 -106 -130.1 +/-52.7 Elo

Data seems to be too badly labelled.
ok thanks for testing, these are only >2800 elo games. The result shall be quite reliable.
