Galjoen 0.36

Post by Werner Taelemans » Tue Jun 06, 2017 7:09 pm

Each element in the countermove table is a history table in this version.
Dividing history after each move also worked:http://www.talkchess.com/forum/viewtopi ... 10&t=63870

But most changes were bugfixes in search and eval (e.g. eval is color symmetric now)

New strength should be above 2100 CCRL.

If you download the source, you will also find the map bin.
This map contains a 32-bit and 64-bit exe.

Galjoen started as a CECP engine. Later I switched to UCI but kept support for CECP.
Today Galjoen is a UCI engine with an extra layer that takes care of the translation between CECP and UCI.
This extra translation seems to hurt more than I expected (especially at short time controls),
and a 13% difference is obviously unacceptable.
The easiest solution, for me of course, is to throw away support for CECP.
I could also try to optimize all this, but I'm afraid that for very short time controls there would still be a difference in strength.
My question: is there in fact interest or demand for engines that support both protocols?

Thanks for testing this. I put this on my to do list for version 0.37, because it's too complicated to do with a small patch now.
