Figured that would be part of the cleaning phase before the evaluation. It's a lot easier to permute the entire set than it is to generate all legal ones at first (at least with smaller sizes). -Josh On 11/7/07, John Tromp <[EMAIL PROTECTED]> wrote: > > I just ran my perm application for 4x4 and

I've put a lot of thought into this. 5x5 is about the largest feasible board size (currently) for creating an "endgame database" which is a table of all possible positions with the resulting score.I don't know if anyone has done this, but I know that this board size can be solved with brute f

You could go the route chess does with egtbs. First permutate every possible board with both stones, and start removing pieces one at a time. I wrote a permutation tool, but even with 3 and 4 size board the end data file was huge. -Josh On 11/7/07, Ben Lambrechts <[EMAIL PROTECTED]> wrote: > >

I think how 5x5 was solved was part of a thesis. I don't have the URL or author handy. 7x7 is semi-solved by a bunch of dans, but no formal proof of its correctness is available. I believe that past work used brute force alpha-beta with transposition tables. 5x5 was made tractable by detecting

I want to create a perfect player on board sizes 3x3, 5x5 and maybe 7x7 and beyond. But I have no idea how to start. How do I create the move database and how do I select the perfect move for every position? I know Go is solved on boards 5x5 and smaller, but there is no program that plays by t
