Pychess+Darwin #57

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago

The pychess eval function is important in many ways.

It contains a lot of hardcoded point values for different things.

* We took the engine out of context, and made it add a little random to all
pointvalues.
* We made it play a lot of times against it self
* Everytime the engine won, the values was frozen, and in the next game,
the two engines evalfunctions would be the ones of the winning engine + a
little random.

So, what needs to be done? What is the issue?

The evaluation function of a chess engine has several component. They has some 
constant values which need to be work together to produce a good final value. 
Tuning these constant manually is a hopeless task, so developers need some 
method to find the optimal values. One method can be some "darwin-like" system, 
Thomas was talking about. Last time I read another promising one here:
