Subject: Speaking of the Thesis by Marcel van Kervinck (hopefully no storms)...

Did anyone notice his cutoff idea in the evaluation function?

It seems to me to be a very good idea, and I don't know if others have tried it
out.

Basically, it consists of three modes with two early exits...

1. If the material + structure score alone is dominant enough, it exits right
away.
2. Otherwise, it processes the piece list.  If that score is dominant, it exits.
3. Otherwise, it does a full board control scan for all 64 squares.

It is described starting on page 62 under the section "3.3.2 Multi Staged
Design"
He gets roughly 71% evals returning in stage #1, 13% in stage #2 and 7% in stage
#3.

It seems like it might be a big win to do it that way.
