automatic tuning of parameters

Post by elcabesa »

do you know if there are any tool that can be used to automatically tune engines parameters?

or should i create a tool for myself? I'd like to try something like a genetic algorithm

The current version only works with Win/Loss outcomes (no draws). I am working on a chess version with draws. I expect to make it available very soon.

Here's a 1998 paper about using Temporal Difference learning to tune eval parameters in KnightCap.

Maybe it would give a starting point and then you could hand-tune after that.
