Go up one level in this thread


In most cases I get all the information I need from one or a few indirect memory
lookups, that's not too slow IMO. In my case, the Attackboard is used in
conjunction with an efficient conventional representation. I do feel that it's
correct to incrementally update variables that are used to either improve move
ordering or create cutoffs. As for speed of implementation I cannot really
compare figures, since I reuse a lot of data i.e. the behaviour will be
asymptotic (and very fast) and not representative of its behaviour on a
completely new position. But on closely similar positions (for example a
sequence of positions in a line searched) it has a good performance.
