Galjoen 0.36

[Werner Taelemans]

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.

Is there an exe for download?

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

I have used Galjoen 0.36 under Arena in both WB and UCI mode and it seems to me it plays weaker in WB mode.

Against a pool of opponents it scored 42 out of 102 in WB mode, then 83,5 out of 154 in UCI mode.

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?

My question: is there in fact interest or demand for engines that support both protocols?

I can't answer this question. I have never really understood the difference between these protocols. When an engine is UCI only, I use it under Shredder, Fritz, Arena and WinBoard alike. When it is WB only, I use it only under Arena and WinBoard. So it seems I have a bias for UCI but infact I only want to avoid external adapters.
When an engine supports both protocols I use it as a WB engine under Arena for the very reason to detect implementation flaws. That's why I started my tournament with Galjoen WB.

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.
