Re: Rapid or blitz

I now see that the FMJD does have definitions for these terms, and game time 15 min per player is included in both categories. http://www.fmjd.org/?p=annex. I think you can use either one.

Re: Rapid or blitz

https://en.wikipedia.org/wiki/Fast_chess. In chess, 15 minutes per player is rapid. I'm not aware of any different definitions for draughts.

Online Computer Olympiad 2020

I received this from Leo Nagels: As most of you will already know, the Computer Olympiade in Santiago de Compostela in September was cancelled due to Corona measures. I am happy to announce, that about a week ago I was mailed by the ICGA president Jonathan Schaeffer, that there still will be a Compu...

New kingsrow version and DTW database

I have released version 1.62 of kingsrow, both hub and UI versions, and a Distance to Win db. When the game position is a win or a loss and in the DTW db, kingsrow will display search results like "white wins in 89 ply". Using it allows kingsrow to play the shortest path to a win. Except for minor U...

Re: Edeon Sport

Can we see some data please? Play a couple of games and record the search scores from Edeon of each move. Post it here.

Re: Flits self-learning mode

I haven't heard Ed say he approved all this. Bert asked me for the code, I gave it to him without any restrictions. If that upset the balance of draughts competition then I am to blame, not Bert. Sure tournaments are fun, but really Fabien has already won, the strongest engines are using his patter...

Re: Opening book stats

To satisfy some people's curiosity, can you run a test with Flits and the anti-Kingsrow book?
JJ, I have a few other things going on this week so I'm not going to take this on. Anyone with flits can run it though.

Opening book stats

I was curious to know how much the use of an opening book can affect a match result, so I ran some tests. For the first set of tests, I played 2 matches of kingsrow vs scan, one match with books enabled in both engines, and second match with the kingsrow book disabled, but scan's enabled. The kingsr...

Re: Flits self-learning mode

It's not about copying the opening book, it's about countering another program. Suppose Kingsrow were only available from a website, but with HUB or DXP API to play against. And suppose you would mask the response time from book moves to make them look like Kingsrow was actually thinking about each...

Re: Flits self-learning mode

Recreating another engine's book from black box reverse engineering seems entirely above board to me. So not looking at the binary files or doing de-compilation, but just playing 1.5M openings and logging when the reply is instant should give you the entire variation tree but without the various ev...

Re: Flits self-learning mode

Another reason might be the cognitive load from learning new tools and also the tight coupling of different parts of a software program that is a common pitfall. Take e.g. your own Kingsrow GUI. It looks beautiful and works like a charm, and I have nothing to criticize about it. But I bet now that ...

Re: Flits self-learning mode

Well, I see I picked a good day to go kayaking, instead of reading the messages on the Forum :-) Rein, to answer your question about TDam, yes I think Klaas will soon be releasing a version that interfaces to kingsrow-hub. The gradient descent code itself is probably best done using a professional l...

Re: Flits self-learning mode

JJ, thank you for your comments. Ed, can you share the results of Kingsrow vs Flits+SidikiBook? Like you, I would be surprised if Flits became very much stronger but why leave it up to speculation? I didn't run the experiment, for several reasons. - I didn't fully understand how to enable and disabl...

Re: Flits self-learning mode

I don't fully understand how this book was created, and I'm not sure that I think this is an acceptable thing to do from a "fair competition" point of view. You could probably copy the entire kingsrow opening book off 1.5M positions with a little bit of programming, and use it in another engine. Do ...

Re: Flits self-learning mode

Ed, I am asking you. How to check if there are errors in the tip database in Flits.
Without any details of how the data is stored in the files, I don't know of any way to check it.
