Andscacs - New version 0.85

Post by cdani » Fri Jan 22, 2016 12:53 pm

I published a new version, 0.85.
Changes:

* Solved little bugs.
* Improved evaluation of knights.
* Improved evaluation of pawns.
* Improvements on king safety.
* Improvements on space evaluation.
* Improvements on opening phase.
* Some small speed improvements.
* Fixed ponder mode.

Seems not much stronger, may be 15-20 elo, but I expect it to scale better at longer time controls or with more processors. Will see :-)

Muchas Gracias my friend. When you say is 15-20 elo stronger, I suppose in reality you mean it is 50 elo or more we can count on in long games. :) :wink:

If somehow I had recovered some scaling I do not discard something bigger than 20, but is just impossible to test this as you know. I prefer to not have any special expectations. Will be nice for example that CCRL 40/40 will have more elo than 40/4 :-)

I know that you have more than 15-20 elo improvement up your sleeve.
In long games and on more cores you can add 30 more :o

The aim of the version is to try if without much modifications, mostly hand tuned stuff, I'm able to improve the long time control clearly. Is for this that I published it without much improvement at my basic testing time controls.

Next version I should publish with more improvements or at least less often; if not I will drive crazy all kind testers like you :-)

Nice to see another progress of your engine. Do you plan to add support of syzygy tablebases? Andscacs does not understand e.g. rook endings where white has a+c pawns and it is known draw, but evaluation is +2,45 for a long time.
