100 game 4+2 match currently running on the slower Athlon 64 x2 system with above time management settings -- after 58 games, +19/=30/-9 in favor of IvanHoe.

Can you theorize why turning off AllowInstantMoveFromHash seems to increase ELO?

Can you theorize why turning off AllowInstantMoveFromHash seems to increase ELO?

Hey Ben, what AllowInstantMoveFromHash does is try to gain time advantage by moving quickly on hash it -- that is if the opponent played the expected move. For simplicity, you could compare it to move on ponder hit. As you see, it says to turn it off when pondering is enabled. Can you see why it would have some side effect?!

here is the code:

Code: Select all

 /* "PREVIOUS_FAST" is inverse named plus don't too this with UCI_PONDER */
  if (EXACT_DEPTH >= PREVIOUS_DEPTH - 6 && EXACT_MOVE == HASH_MOVE
      && !UCI_PONDER && EXACT_MOVE && PREVIOUS_FAST && PREVIOUS_DEPTH >= 18
      && ALLOW_INSTANT_MOVE && MyOK (POSITION, EXACT_MOVE)
      && Value < 25000 && Value > -25000)
    {
      ROOT_SCORE = Value;
      ROOT_BEST_MOVE = EXACT_MOVE;
      ROOT_DEPTH = EXACT_DEPTH;
      PREVIOUS_FAST = FALSE;
      if (!IsCheck)
	v = MyExclude (POSITION, Value - 50, PREVIOUS_DEPTH - 6, EXACT_MOVE);
      else
	v = MyExcludeCheck (POSITION, Value - 50, PREVIOUS_DEPTH - 6, EXACT_MOVE);
      if (v < Value - 50)
	return;
    }

Sample long (40/40 repeating) games being tested on 2 systems. Exact positions and engine settings. The difference is, No EGTB for the much much slower hardware, and of course, Hash is scaled to fit each system. This is a preview on how Rybka/IvanHoe manage time. The sample games can be plugged into your favorite GUI -- and you can see how they spend time through 40 moves, including difficult and not so difficult positions. Rybka is using recommended Time management configuration for repeating games as is IvanHoe. Use drop menu to select game, E1 to move forward, D1 to move backward, and D8 to get full PGN source.
