Re: UCI pondering done right

I find that making pondering rely on the behavior of hash table on a new search of a different position is even more horrible. What do you mean by "the behavior of hash table on a new search" ? There is only 1 possible behavior, which is to do nothing. Unless, of course, you are debugging your engi...

UCI pondering done right

I find the UCI pondering spec truly horrible. It violate both UCI key principles, to the point that it feels like a piece of Winboard grafted on UCI: (1) statelessness. (2) simplicity for engine developers. Instead, I propose a better way to handle pondering, without any change to the protocol. The ...

Re: 90 threads now on CCC 3

The TCEC contest has 44 threads (about half of CCC 3). So why not use 44 threads per engine and have pondering turned on? The extra 2 threads will make the server more responsive and avoid competition when the machine needs to do some internal upkeep. That way, you get double the quality with the g...

Impressive for an engine that has only Material + PST eval. Next version will come with hundreds of elo of eval, and steamroll the competition.

Re: 90 threads now on CCC 3

I am not really sure running with these high core counts is such as great idea because you're taking a program designed for one kind of environment and dropping it into something quite different. There are going to be some inefficiencies that prevent linear scaling. Some engines may do better than ...

Re: LC0 network 31740 vs Stockfish 10

Your reply as well as the upper attempt of "joke" shows how ppl are actually clueless and lack basic logic (and the wonderful irony in your nickname that is actually name of algorithm that exclusively requires CPU to run). Neither SF nor Lc0 nor any other engine can actually run only on graphics ca...
