If anyone is willing to explain the Texel tuning method tht would be great!

Sofar I understand I have to let it play (well, run QS + eval on FENs) millions of games and then do something with the evaluation-value. But what? I don't understand the wiki explanation.


The basic idea is pretty simple: calculate the error of the evaluation when it is compared to the actual outcome of the positions. Lower a particular evaluation parameter and check if the error has improved, if not, higher the parameter, if again not improved, keep the original value. Do this for all parameters until you have reached the lowest error.


This is the local search algorithm but I would assume that it is better to run some gradient based algorithm first (Maybe gradient descent or gauss-newton). Then if the error doesn't change by much anymore I would switch to local search.

I am going to implement texel tuning this week and see what I get Razz
