Go up one level in this thread
Certainly 5.0b is better than 4.1, which was the previous released version. Whether it is master level or not depends perhaps on the hardware. On a 233 MHz machine, which I use on FICS, it is still losing games to human masters and experts, especially at slower time controls. It wins some, too, but it is far from invincible. I tend to think of a "knowledge-based" program as one that uses chess knowledge to guide the search, either by selectively pruning out "uninteresting" moves (Shannon Type B strategy) or extending lines based on something more sophisticated that the standard check and capture extensions. In this sense, Arasan is not a knowledge-based program. It has a fairly complex evaluation function and "understands" many positional concepts, but it uses this knowledge inside a fairly standard search framework with commonly-used extensions. I have a newer version with a much faster hashtable implementation and a couple of bug fixes, which I am hoping to release in the next month or so. It has been doing well on my test suites and in games. --Jon On March 24, 1999 at 10:32:38, Fernando Villegas wrote: >Hi John: >I have been following your sucesive Arasan incarnations and I can say you that >it seems you have reeached the level where Arasan can be considered at least as >fide master and maybe more.
