Re: Don't use databases

After training a network it saves network weights in a database. But once in a while it fails. So all tuning was for nothing for new weights weren't stored. Message: Test method Skipper3.Tests.NetworkTest.TrainNetwork threw exception: System.Data.Entity.Core.EntityException: The underlying provider...

Re: 140 - CCLS Season 5 - Entry League (64 engines)

Demolito 2018-03-01 x64 ===> NEW ENGINE Demolito does not ponder. In fact, most engines don't ponder, because it's an annoying feature to implement (due to mis-designed UCI spec). So you should check that all these engines actually have an UCI Option called "Ponder". Lucas, can you take a look at t...

Re: Lazy SMP ideas

So here are the test results from my implementation of ABDADA and Lazy SMP from the new engine and the modified YBWC from Hannibal. I'm using the following set of positions (from Hannibal games and from some positions posted here in CCC): "r3k2r/pbpnqp2/1p1ppn1p/6p1/2PP4/2PBPNB1/P4PPP/R2Q1RK1 w kq ...

Re: Minimalism in chess programming

Yep :) That's what I am actually doing now. I did this before using vice to calibrate my previous engines but they all had separated MakeMove(), TakeBack() etc. functions compare to one I'm currently working now, but nevertheless I've managed to print root nodes internally (like internal iterative ...

Re: Ivanhoe plays singlecore in TCEC 13 !!

In the past when Martin was still in charge of TCEC each engine was thoroughly checked before it was entered in the tournament. Now it seems more like playing Pacman. TCEC will lose a lot of credibility with all these nonsense. TCEC tournament director is totally incompetent. Was already the case w...

Re: texel tuning

Am looking at texel tuning. From the wiki: "K is a scaling constant. Compute the K that minimizes E." How to do so? Its trivial using the Newton Raphson method. What you want to compute is K such that E'(K)=0. Don't they teach this at high school anymore ? Also the wiki says to run a QS. But if I u...

As long as it works, and is free to use, I don't care. Of course, Github is losing money, and ...
