Re: ABDADA+ suggestion

ABDADA (and YBW) are both speculative algorithms: they do work hoping that the work was not wasted. It would seem to me that the goal of speculative execution is to do two things: 1. Select nodes (and subtrees) that have a high-chance of being necessary work. 2. Avoid nodes (and subtrees) that have...

Re: ABDADA+ suggestion

There is no need for the intermediate step because when you do (3), the first thing the search does is check the hashtable and it will find hits if the children have been search by other processors.

ABDADA+ suggestion

I have implemented ABDADA on gpu and it achieves an time to depth speedup only up to 32 parallel threads resp. workers. With more than 32 workers there is not much to gain, tested it with up to 256 workers, but not at longer time controls. Looking at the algorithm and game tree, I think by adding an...

Re: Linux flavors - opinions

I use Ubuntu, but one thing about it really bothers me . You have to jump through hoops in order to get a modern gcc compiler on it. The one you will collect by installing the standard programming packages is some crusty, ancient 4.xx gcc from a decade ago. (No, really). I was able to get 7.xx by l...

Re: Linux flavors - opinions

Thinking about setting a Linux environment desktop - leaning towards Ubuntu since it’s on the Pi and I already have some some familiarity with it there. What do you all suggest and why - Pros and Cons. Thanks in advance for taking the time to respond. MikeB I can recommend Ubuntu, using it since 20...

Re: CCRL 40/40, 40/4 and FRC lists updated (15th June 2019)

Thanks, OK I'll try it without that first of all. I run Windows 10. Do you have a rough estimate of CCRL blitz Elo for it ? It depends on the hardware https://www.chessprogramming.org/Zeta#NPS_and_Playing_Strength iirc 2200 Elo was reported for an GTX 1080, I guess ~2000 CCRL Elo can be achieved on...

Download, double-click and reboot OS. Increase to 20 seconds, for 40/4 TC for example: https://zeta-chess.app26.de/down...

I've used Arena years ago so could use it again if I had to. I do use Cutechess. When the engine is ready you'll need to give me any special instructions over and above what I'd expect when using a standard UCI engine.
