Andscacs - New version

Hi! I published a new version of Andscacs, 062u. It seems to be minimum 50 elo stronger, but my tests are very limited. Principal changes: * Added information of Nodes per second. * Added Static Exchange Evaluation for quiet moves, for depth > 2. * Some optimizations for speed gain. * Better orderin...

Re: testing procedure

It can be both dangerous and misleading. Suppose you add a complex evaluation term. Testing to fixed depth ignores the speed penalty the new term introduces, so all you see is the upside. But in real games, were time is measured, your program gets out-searched and loses badly. Sure. I was thinking ...

Re: Dinosaurs and Mammals

I think there are a lot of possibilities near us, just must be picked. But I understand that when there is a lot of information on anything, people tends to use it instead of thinking all from start by themselves. Andscacs is an example, where I was able to do a relative strong program with relative...

Re: testing procedure

Thanks also!

Another question/idea I use is, for some type of changes, just play a lot of depth 1 games. I think that is enough for some changes in evaluations.

Re: testing procedure

Thanks to all! Gracias! Sure I will do it. Another idea I used with some success is generate a list of a lot of positions, each with a list of acceptable moves, for example within the range of 0.20: 1B1k4/8/1KR5/1P5q/8/8/7p/8 w - - 0 72 b8c7;b8h2; 1b1r1nk1/1p3qpp/p1p2p2/2P5/1PN2P2/P1B3PP/4Q2K/4R3 b ...

testing procedure

Hi! I use cutechess-cli for testing like most people. I see that when I do matches with my engine against an older version of it, there are a lot of repeated games. I use pgn-extract -D to remove them. But is this normal? May be the book I use (varied.bin) is too little. Also I don't know how random...
