Re: Leela is more Chess-domain specific than regular Chess engines

The RL approach builds a giant evaluation function based on pattern recognition. The positions you present here are obviously irregular patterns and LC0 can make no real use of the pattern recognition. On the other hand, regular engines "break-down" the evaluation function into logical pieces of inf...

Re: A question about speed difference between gpu and cpu

Yes... I am aware of the Stream Processors and that GPU is like a Multi-Core SM

For example, the Jetson has 1 such core. But again the size of the SM is not comparable to the one of the CPU.

Re: Leela is more Chess-domain specific than regular Chess engines

This is why deep residual neural networks perform better. They combine many convolution filters.

They require better hardware to run on though.

GPU hardware is not enough for such a limited time.

Re: A question about speed difference between gpu and cpu

The difference is in the architecture. You use a single command (for example add) to multiple data. So you have 2 vectors V1 and V2. You store them in "register vectors" and adding is just a single command. It does not require any loop. You can also multiply subtract... etc. But complex logic is not...

Re: 3497 elo Leela, possibly 4th best chess engine now!!

A comparison is easy to make and the unit of measurement is, of course, the Wattage. It may not be in favor of CPU's but that is a measure of computing effort Personally, I do not use the engines as "horses" but only as analysis tools. LC0 has a much better position understanding than any other engi...

Re: lc0-win-20180512-cuda90-cudnn712-00

Is there any link explaining all these UCI options?

Also why does it report depth to 1 or 2?

Re: Lc0 NN329 against Houdini 4 in 2 LTC games

My impressions from analyzing with the latest LC0 (330). In positional games, when there are not deep tactics but requires building attacks, LC0 is MUCH better than SF_latest. The main problem has to do with deep straightforward tactics. I do not know if LC0 uses extensions or not in its monte carlo...

Re: Brainfish, a new concept of a chess engine

hi, CAP evals aren't minimaxed. not 'an sich' but they are in Chess Assistant (or Aquarium); however i tried to add some of my own epd files to the cap and minimax again, but then no results show up. lots of these chessok still seem to be buggy; maybe should post on their forum one of these days (t...
