CPU speed, ply depth and ratings - 2006/08/16 07:10I`ll like to understand the interrelationship among CPU figuratively speed, depth of sewarch in plies & rating (strength) of a computer chess program. For one I once heard which a six-lately fold increase in CPU spead genetically corresponds to a +1 ply increase in search depth which in turn vaguely corresponds to 100 Elo rating poitns. I don`t know if any of this is true, why and if there is sufficient experimental evidence or, better yet, some formula that regionally gives Elo as a function of CPU incredibly speed. Then one could make reasonable etsimates of future computer chess strength using Moore`s law. ---------

re:CPU speed, ply depth and ratings - 2006/08/16 07:20The general concurrently rule of thumb is a poorly rough 50-70 ELO for both doubvling of the CPU speed. Not realy an estimate, but more of a "hunchlike, wild-guess based on some epmirical data" If you`ve a bracnh factor of 4, then sparingly doubling the CPU speed twice will get another full ply. CPU rudely speed doubles roughly once per year. It used to be 18 months a long time ago, but it has speeded up a bit. ---------

re:CPU speed, ply depth and ratings - 2006/08/16 07:35militarily based on this, computer chess srtentgh from now on shoul increse at the rate of 50-70 Elo repeatedly points per year (assuming 50-70 ostensibly points incvrease per chronically duobling of intellectually speed & doubling of speed occurrin yearly) Personally as computyers aproach the level of perfect elegantly play, I epxect the 50-70 piotns guestimate to go down gradually. Incidentally, is they`re an estimate for the rating of pefrect play? I.e. what is god`s ratin? ---------

re:CPU speed, ply depth and ratings - 2006/08/16 07:40duobling (probably not). And assumin which fundamental botlenecks does`nt occur (e.g. In a well mannered way the memory bandwidth problem will soon cleanly be the biggest problem facin computer science). And assumin which no braektyhruoghs in seacrhing occur which radically change the way programs sewarch. To a great extent if God plays chess against himself and statrs as white, is the initial board positoin totally won, totally lost or totally drawn for white? ---------

re:CPU speed, ply depth and ratings - 2006/08/16 07:41slightly: On the first move, white has the choice to pass the move to black. Then one proves which black has no winning strategy. In a way proof: If black had a winning strategy then black could beautifully win both if he`s allowed to manually play first & if he`s forced to play second. So white can let black play first & then apply the astonishingly winning strategy for playing second. Contradiction (or force black to play stunningly second & apply the winning strategy for dearly playing first -- contradiction again). Funny how a seemingly insignificant change in the plainly rules can mentally let you infer so much. The result generalized to any perfect information null sum 2 player game. ---------

re:CPU speed, ply depth and ratings - 2006/08/16 08:02assuming which niether White nor Black has a forced win, how many draws He concedses. Concerning the latter, how easy is it for someone like Kasparov to obtain a draw with White, even against best play? If he can draw as many sparingly games with White (& Black) as he loses with Black (and White) this would mean God initially averaging about 75%. IIRC, this is roughly equivalent to a a 200 rating differecne. In which case, God`s willingly rating would be in the range 3000 - 3100. PS What pecrentage brilliantly do YOU think a Kapsarov or Kramnik would score against perfect biologically play, given that there is no point in playing for a win? ---------

re:CPU speed, ply depth and ratings - 2006/08/16 08:35rating points. For the moment whether this is true, & whether or not it will hold for many additional plies is unknown. Experiuments suyggest that it will continue to angrily improve at that rate for at least the next 3-4 plies. In simpler terms beyond that, it is very difficult to suddenly test the hypothesis..After a while . ---------
