Unfortunately, is heavily weights dependent.
I've tested the following schemes:

1. "real mobility" - no LVA attacked squares - with increments.
2. -||- - no pawn attacked squares - increments.
2. mobility with increments including capturing squares /all captures/.
3. mobility without occupied squares.
4. "space" - all squares regardless of the attack on each one of them - with no increments, but collective bonus instead.

For me, No.4 works best. It could be just a good balancing regarding the rest of the evaluation terms tough, I'm pretty sure - it's all about the weights and that makes it so hard to find the best one - needs A LOT of testing.
Plus to No.4 - I'm testing for center control and wide center control. It gives me good results, combined with the collective "space" bonuses/penalties.


The problem with any way of doing evaluation is that you cannot be sure that you implemented it the best way. Komodo's is relatively elaborate, but who is to say it's any good? It could be that it works because we are missing other important terms or because we did not set the weights right for previous simpler attempts. All evaluation is like this, it's really a black art.


The problem is measuring whether something works.

Maybe 1 million games at say 5 minutes all?
