Re: Updating engines mid-tournament

Ah, yes, Leo Dijksman as well!

So happy that the CCRL is still going strong and also doing fun tournaments.

Re: Updating engines mid-tournament

Agreed on all points. On the other side, you would have (for example) Olivier Deville's excellent ChessWar and OpenWar tournaments, in which each round took 1-3 days. If you saw your engine do something stupid, or were working on something that you weren't QUITE finished with, you knew you could get...

Re: Elo boost and time management

Skipper using timeLeftOver/ 60. Doesn't understand increment. Hardly ever looses on time. On the contrary it loses because of using too less time. so even if movestogo is given you assume that you have 60 moves to go? What is movestogo. How do I get movestogo ? Game may last for 350 moves or more. ...

Myrddin disconnected after 6 rounds, and had to be forfeited.
Very sorry about that. My wife assured me that she had set her new laptop, which is much faster than mine, so that it wouldn't go to sleep when not connected to power. Oh well....

Re: Swiss Tournament. Edition VII. Group C.

Thanks for the tournament, Sergio! Too many draws against weaker engines for Myrddin to advance, which is probably fine! :)

Re: Swiss Tournament. Edition VII. Group C.

Yeesh. Ugly play by both Myrddin and KnightDreamer. I doubt you'd find a position like this in SF v Komodo games. :D

Re: Simplest way to implement quick and dirty lazy smp

Yeah, I used that in my engine HaQiKi D, also with satisfactory results (eventually). I don't connect the processes (by pipes) in a star topology, though, but as a linear chain. When a process receives the command "cores N" with N > 1 it launches a daughter process, and passes the command "cores N-...

Re: Simplest way to implement quick and dirty lazy smp

Ok, so just say you haven't got a clue about lazy smp, and are looking for a very quick and dirty way to add to a non-smp program.. which is written in C. What's the easiest and simplest way to implement? Where's the best start point? Well, if your code is not thread-safe and you REALLY want the QU...

Re: Quantifying progress && Naked WAC

That doesn't seem possible. It used to be that tuning your engine for maximum score would actually decrease its Elo. (Not sure whether this is still the case for modern engines.) As extremely weak engines (e.g. with hardy any search depth) would also not score very well, that would mean any relatio...
