Re: Wizards v Warlocks Teams Match

Thanks as always Graham.

This types of formats are always interesting as they bring together engines that would normally not be grouped together.

Also, looks like Cheng scored a world first. Gained an extra .1 points for flair!

Re: LCZero update

I think he has a couple of 1080TIs and maybe another 1080 or something like that. My old AMD card does 2 Tflops. I started this morning and it is up to 15 games. I guess it will make 50 games in 24 hours, which is about 1% of Error323. I looked up the specs for the Nvidia Titan V and it does 110 TF...

Re: Sabrina profiling

Remember that these numbers are only relative to the total CPU time of your program. If I wrote each method twice as efficiently I would get the same numbers as I do now.

Re: Sabrina profiling

I am assuming you mean generate moves when you say "makeMoves",

In Nirvana,

Evaluate: 35%
Generate moves (includes sorting): 18%
Making and unmaking moves: 6%
Is checking: 5%

The other large time sinks are ttProbes and see, which take 7% and 5% respectively.

Re: Threat detection

IIRC Stockfish had a concept similar what you are describing here. Whenever a null move failed low, SF looked at the move that failed high for the opponent. Every move that prevent this move from being able to be played (by moving in between the from and to squares) was then reduced less than it nor...

Re: Ordering Capture Moves

I'd certainly be interested to see what you come up with (even if it ends up taking more than 8 hours). Exchanging information between nodes like the way H.G. described isn't something I've thought of before so I'll definitely add that to my list of things to try out. Just as I had predicted the id...

Re: Ordering Capture Moves

Now that we are talking about ordering of captures: How much sense would it make to try to learn from what happened in a sibbling node, rather than rigidly adhering to the static MVV/LVA + SEE ordering? Just as you use killers to get the best non-captures in front. Usually the hash move does the jo...

Nice! It looks like you got it all working. Sorry it was so hard to track down exactly what was wrong.

Re: Nirvanachess 2.4 has been released

I see it calls itself Nirvanachess Chess which seems a misspelling to me, what is the correct name? Hmm I didn't notice that. It should be "Nirvanachess". I will fix this when I get back to my computer next week.[/quote] This has now been fixed. There was also a small performance improvement that I...
