Please write what happened that you don't want to participate in the tournament.
In light of recent developments I lost interest to compete.

Re: The Unofficial World Championships Of Computer Programs In International Draughts Blitz 2020

In my opinion an independent expert should investigate the claim that Edeon Sport is using Scan 2's eval. But that is up to the community.

Re: The Unofficial World Championships Of Computer Programs In International Draughts Blitz 2020

As I already told Krzysztof, I decided to withdraw Maximus from the unofficial world championship 2020. For the people who have Maximus this means I am revoking the rights to let it play in computer tournaments, matches, exhibition games, etc. I trust you will all respect this. Krzysztof, please rem...

Re: Flits self-learning mode

Ed, it is very gentleman-like of you to take the blame. So you are not going to share with us with what intention you gave the code or what you think of what was done with it. Don't you think Damage eval derives a lot from Kingsrow eval this way? More than Kingsrow eval derives from Scan eval, I wou...

Re: Flits self-learning mode

Yes thank you for sharing, Fabien. The Edeon case seems clear, if there is proof they should be banned. But of course they can hide it now if they want. I recently checked where my app for Android can be downloaded for free, not funny either. Now I have other problems: try asking Google and Samsung ...

Re: Flits self-learning mode

Fabien, thanks for your answer. I did ask others or rather everybody since this is a public forum, but so far only very few people have joined the discussion. And "the" opinion seems to be that this is allowed, although I only count you and Rein (not competing himself). What do the others think? (Ed...

Re: Opening book stats

Ed, thanks for running these tests. As expected the book difference is small for strong engines. To satisfy some people's curiosity, can you run a test with Flits and the anti-Kingsrow book?

Re: Flits self-learning mode

Of course, who contributed to the data should be mentioned. I'm not saying everybody should be constrained to zero knowledge and that all dependencies should be banned. I suppose it is normal to train on games played by previous versions of your engine, on games played against other available engin...

Re: Flits self-learning mode

Although I don't use 3rd party libraries, I'll take a shot in the dark and give Jan-Jaap a possibly-missing piece of the puzzle. At first sight, it seems far fetched that those libraries could help learning patterns at all. However, from what I consider a historical coincidence, Natural language pr...

Re: Flits self-learning mode

JJ, do you believe that the strength of Damage is only based upon the optimization program? No, but see last year's tournament. Although Damage was running at 1 thread then, I believe, which makes a small difference on 4 cores. I think Damage with old eval is at least 100 Elo weaker than Damage wit...

Re: Flits self-learning mode

I previously already stated that programmer collaboration that refrains from copying code / weights into each other's programs should be allowed. Why would it matter that the ML code is private? Scan has private ML optimization code. Suppose Fabien shared it with a few French programmers. Who cares...

Suppose someone came in a tournament using Ed's endgame db driver? Would that be "powered by Kingsrow"?
You know very well this driver is public, and it was only for practical reasons (no Elo difference).

A lot of text now. First I would like to know if Ed does confirm Bert's account.

Re: Flits self-learning mode

Rein, thanks for expressing your opinion. I think you will agree with me that using somebody else's tools can only be done with the author's permission. And that has not been established in this case. The gradient descent code itself is probably best done using a professional library. I doubt that, ...

Re: Flits self-learning mode

Interesting discussion. ... So yes I have an advantage by starting quite young, and being 63 (close to retirement :D ). Bert Bert, It is clear that you could not have done it without the extensive help of Ed so your account of the situation is not credible. Once someone shows you how to get a first...
