Re: An idea for a new WCCC format - what do you think?

A simple solution to catching cheaters? Another anti-cheat could be to require upload of log-files of thinking output for all (or a selected bunch) to see. Cheating then would still not be impossible but made a bit harder. Stan This is a good idea. To prevent or stop most accusations of cheating at...

Re: An idea for a new WCCC format - what do you think?

A simple solution to catching cheaters? Why not have everyone who enters the tournement be required to send a copy of the engine that they inend to use in the tournement to the director. In that way if someone is accused of cheating then the game could be replayed by the director using the engine s...

Re: An idea for a new WCCC format - what do you think?

My main point against a live tournament would be that for whatever reason the internet coverage always seems to suck, even though it's as least as important as the event itself. I should be well possible to have both working well, but I can count the events where I have been to and things were OK, o...

Re: An idea for a new WCCC format - what do you think?

There are 2 strong points in favor of having a live tournament: a) It's easier to get sponsors and publicity. And hence, rewards both material and nonmaterial, for winning! b) It's human nature that the incentive to cheat is less if you are facing a person rather than in the anonymity of the interne...

Re: An idea for a new WCCC format - what do you think?

Is there some evidence to suggest that this is true. For example, a past CCT winner who you think did something like this? Formally, everything you can do in an internet tournament can also be done via remote play. Vas There were disputes about Junior and SearcherX in the past. And that's only thos...

Re: parallel search (technical)

Can't you achieve what you want by requiring that the first node searched (which is always non-split) took at least x nodes before allowing a split?

Re: Intel to detail eight-core Xeon processor

Sounds interesting ... personally I would really like to get my hands on an overclockable "Skulltrail" type platform for 2 x 8core Nehalems. Imagine 16 cores at 5ghz !!! I think after 16 cores the advantage of hardware for chess gets diminishing returns and thus a different method such as clusterin...

Re: SMP and helpfull master concept

My point was that I am willing to split _anywhere_. Sure you can, but that doesn't make that SMART :) Let me put it differently: your helpful master can go help the search for move 2 out of 20, or it can go help the search for move 20 out of 20. I'd rather have my master do the first than the latter.

Re: SMP and helpfull master concept

Another trick which you can try is to only allow the master to help in subtrees below its own splitpoint. Why the limit? I let the "master" help anywhere in the tree... IIRC this gave a small extra speedup on low numbers of CPUs at some point. I no longer do this, though. It will also save splitpoi...
