It is a ridiculous statement. Only down-side is that I doubt I will live long enough for the idiocy of that statement to be prov...

Re: Checkers Solved - Chess around year 2060-2070!

Sorry, but you can't _prove_ until you do search all pathways. That's the very definition of proof. "we think" does not mean "it is". Funny Jonathan found a better way! What other way? He pruned out the BS, concentrated on wins and draws etc. He reduced the problem by a huge number of useless posit...

He uses a classic "best-first" search. This way as a branch reaches the database and gets an absolute score, it is...

Re: Checkers Solved - Chess around year 2060-2070!

I think that chess will be solved but not by conventional thinking. It already seems that chess is a draw because till today not a single opening has been found that guarantees a win with best play. While it can get a win OTB, others can always find refutations and manage to equalize. So it seems f...

Re: Checkers Solved - Chess around year 2060-2070!

I just solved chess, on the back of my hand, cool!! But seriously, I read somewhere there were 10^125 possible games, and that a quantum computer could do it in a year, but its nonsense. I think theres 10^80 or a bit less atoms in universe, so you need 10^45 universes of atoms to equal number of po...

Re: Checkers Solved - Chess around year 2060-2070!

It takes 2^160 bits to encode a chess position. And that ignores the 50 move rule and repetitions. To prove the game won, lost or drawn is _far_ more than just enumerating all the possible positions. Pathways have to be included and that turns this into a _huge_ problem. And "huge" doesn't really d...
