Hi All,
I would like to know whether updating attacks_from/attacks_to arrays in
make/unmake move is efficient or calculating this info whenver needed is
efficient. In my last chess program I found out that over a longer program run
both turn out to be equally efficient. I mean the fact that updating
attacks_from/attacks_to for all squares (some of which might not be used at all)
turns out to be equally bad/good as compared to calculating it from scratch
every time I need it (mostly in eval or check detection);
What is your opinion ?
regards
tomar
