Re: re-inventing the SMP wheel

There is a major flaw with this unsynchronized approach that absolutely kills it. What do you do if two or more nodes start at the same position at the same time? They get no hash hit, they all search the same nodes in the same order, they provide no increased performance. This is exactly what I pr...

Re: a program that write chess programs(can you do it?)

the problem is, those do the same thing. It is like the days of "gotoless programming" where everyone found bizarre ways of eliminating the goto, without really eliminating the goto.

Re: a program that write chess programs(can you do it?)

it would be trivial to do it. But the savings would be extremely small. And it would make the program harder to tune for individuals that like to do this. It takes me 10 minutes to compile Crafty (using PGO) at a minimum. Who would want to wait that long to adjust a parameter and then play a game?

Re: Something wrong with the testing at CEGT?

Very "nice" headline :evil: What if there is something wrong with the 4CPU implementation inside Deep Fritz 10? Actauly,there are a lot of engines which perform better using 2 cpu's and CEGT is not guilty at all,this phenomena is observed in other rating lists.... It speaks to some testing issues. ...

Re: Time for Being The Nice Guy Is Over

i want to make it clear once again that i am IN NO WAY a part of any concerted effort to discredit anyone..if one even exists which i highly doubt while i stand in direct opposition to Banks candidacy it is chiefly because i simply think we should have new mods and not the same one for what will am...

Re: nondeterministic testing

As is the times that you use for the games? The number of games will depend on the changes that you make in your program. With great changes you will need less games and with small changes you will need more. 60 Nunn games, 3 or 4 opponents, 40/4 is ok for me. Run the same test 4 times and then rep...

Re: Questions regarding the Election and Nomination Process

(1) if you delete profanity, you change the meaning of the statement. "that is bullshit" becomes "that is <blank>" What is missing? "A great f***ing idea" or "a piece of sh**"? (a) "A great f***ing idea" would not be edited (except perhaps to add the stars). Only abusive or offensive statements are...

Re: nondeterministic testing

I am in the process of developing a better testing strategy for testing eval changes than the ad-hoc methods I've used for forever. I've read on several occasions that most use Nunn type matches to remove the randomness of the opening book selection. I ran Prophet vs. GNU 5.05 at 10 5. The results ...

Re: Questions regarding the Election and Nomination Process

I simply don't like either the actual events that have been happened, nor the potential actions that could be taken to abuse this particular feature. Adding or deleting words or sentences makes it too easy to completely change the meaning of a post, whether it is intentional or not is irrelevant......
