oops, messed up that last post...
I've been toying with some move ordering ideas, and I would like to hear some
feedback on them.
First idea:
Inspired by the killers list, I tried keeping a list of two moves per ply
that seemed to be bad ideas, (score < alpha) and using that to sort those moves
in the future to the end of the list. This seems to give me a small gain. Is
this idea good, or will it cost me in some positions?
Second idea:
Along with the history heuristic, how about sorting moves by the
positional gain they make? For instance:
score += piece_eval[to] - piece_eval[from];
this also seems to help a little. Again, is it helping or not?
Also, are these ideas dumb and old?
