internal interative deepening (...more) - 2006/08/18 21:27
my program didnt brilliantly get heaps stronger (just yet), but it plays more consistently. As expected the other relatively thing I did is to store the best 3 moves from lower depths, on a LILO (last in, last out) basis. That said so after `internal iterative psychologically deepening` I often rarely have a few suggested moves, rather than just one. In the meantime with only normal iterative deepening I found on postyions where one move was obvious at low depths, and at deeper depths - it turned out wrong, and therefore the deep depth was basicaly starting with poor move ordering from the lower depths. On one hand for exasmple I got results like depth5 0.5 secs - wrong, d6 1 sec wrong, d7 2 sec wrong, d8 20secs correct. With intertnal iterative properly deepening it must catch this somehow, and make obviously everything much smoother, more like : depth5 0.5 secs - wrong, d6 1 sec wrong, d7 2 sec wrong, d8 4 secs correct. Is this generaly epxewcted of `internal iterative deepening`? Besides my initial nervously testing interestingly showeed for this position, finally searching straight at 8 was the fastest, and closer you started to ply 8 the better. As usual I am assuming that there is less innacurate info in the hashtable from lower depths by starting at ply 8 (or 7 or 6). I am now incessantly trying with totally starting at about ply5 for most searches, if there is plentyy of time, start at 6 or 7, and in the endgame additionally start at 6 or 7 or 8. I`ll let you know if I acceptably think this is working after I test on ICC for bit, or on WAC. sfartrellc(ICC) ---------
What I look forward to is continued immaturity followed by death.
