Re: Genetical learning (again)

I use genetic tuning in my own little chess program. Pretty much every part of the program can be either tuned or turned on/off via these parameters. I tend to let it play itself for say 100 games and altering one param at a time. I appreciate that this isn't optimal but it's enough to highlight iss...

Average search depths

Just curious but what depths do modern chess engines search to (say if thinking time is 1 sec). I'd assume bad moves would be removed at lower search depths and after that it would depend depend on the number of pieces on the board and how good the move ordering is etc. Could anyone give me some rou...

Re: Strongest MPI-capable (cluster) engine?

I posted the article because it was fun and directly relevant to the OP. I certainly didn't expect this cluster to independently develop consciousness and then solve the worlds issues. :wink:

Tom's Hardware recently did an article on a cluster of 64 RasPi's. End result was a 11 GHz of processing power and 1TB of memory - not sure if this really counts as supercomputing these days but the pictures of it are great.

Re: fuzzy endgame databases

I'll quickly restate that I'm not using this in a chess program - my own little chess program has no end game database at all and instead just switches in different scoring algorithms depending on the position. For checkers it's different because you need to search much deeper to see that a given mo...

Re: fuzzy endgame databases

Yes you can store only one side to move tables if you are willing to do a one ply search during probing. I actually check the "database" at the leaf nodes. If the position is stored then I'll return the score associated with it otherwise I do my normal scoring methods. I do actually check to see if...

fuzzy endgame databases

I'm trying to improve on the end game database in my checkers (English/international draughts) program Diamond Draughts . I could obviously store every position possible and it's corresponding score but I haven't got the inclination to gather that much data and there's no way my web based java progr...

Re: What is the fastest single core CPU now adays?

Sandy Bridge is last year's news ;) Check out the i7-3770K, it's not as fast as the Xeon I linked to, but it's probably the fastest quad-core desktop CPU out there. Personally I use AMD because I don't like Intel's monopolistic practices and AMD provides good value-for-money, but if you absolutely ...

Re: What is the fastest single core CPU now adays?

Not sure you can buy a single core chip these days. Personally I'd go with an Intel i5 2500k and you'd want the latest sandybridge version. It has 4 real cores running at 3.4Ghz but the chip is totally overclockable - with reasonable air cooling people get around 4.5Ghz. Cost is about £160. PS you'd...
