Re: ICGA's 2015 World Computer Chess Championship/Events
After a long while (several years) I tested some good CTG books, I got some taste after seeing polyglot ones. Yes, using the latest Stockfish, King Asad Vipre from January clobbers at 1'+1'' both ChessPro 1337 from November (300 games, +39 -9, the rest equal, high draw rate) and the BooksWar champion Rising Star from December (100 games, +36 -2, the rest equal, lower draw rate). I suspect that the later King Asad Vipre (January) is tuned against the two strong, but earlier books.

Re: ICGA's 2015 World Computer Chess Championship/Events
Thank you Kai. I have been committed to 1337 for sometime, but King Asad Vipre version 5 if I am not mistaken has just been released this February, so I will probably go with that. The book is a lot cheaper too. The only issue is that I do not use CTG; I only use .bin books in Winboard. I do not know if the author is willing to create polyglot versions of his books. I've heard it's easy.Laskos wrote:After a long while (several years) I tested some good CTG books, I got some taste after seeing polyglot ones.

I cleaned it, and a I am releasing the code and binaries.Laskos wrote:Thanks, that is very close to my results (52% draw rate for drawelo 200 and equal opponents). In fact I used a hacked in 5 minutes simulator for TCEC, where the drawelo_var was a variable function of Elos of opponents as drawelo*Elo/3200, with SF and Komodo Elo at 3200, and drawelo of 260. This is a gross approximation to take into account the strength of engines. When hacking the sim, I set drawelo 200 for WCCC, but inadvertently kept the dependence on Elos.michiguel wrote:I used 64% just to compare with Peter's. Just to make it clear, this is between equal opponents. Between opponents of different strength scales down automatically.Laskos wrote:I used drawelo of 200, which gives lower draw rate than your 64% for equal opponents. 64% seems a bit high, it's valid only for several top engines, the rest have lower draw rates. Can you use 56%? Probably my drawelo of 200 is a bit too low, though.michiguel wrote:
I have the feeling that using books may increase white advantage. Anyway, simulations with 30 elo of white advantage are below.
Tie breaks are not applied. Those cases are the ones listed as "shared". When there was only one winner is listed as "outright".
I can try to implement some SB rules.

Code: Select all
=========== Color when 1 plays white against 2 Total engines = 11 Total games = 55 Total rounds = 11 Total boards = 5 Total cycles = 1000000 draw rate (equal strength) = 64.0% White advantage = 30.0 rating[0]=3200 rating[1]=3100 rating[2]=3050 rating[3]=3000 rating[4]=2950 rating[5]=2900 rating[6]=2700 rating[7]=2700 rating[8]=2200 rating[9]=2200 rating[10]=2200 won = 622003 shared = 177919 loss = 200078 total = 1000000 won outright % = 62.2 <=============== won shared % = 17.8 ======== Reversed colors Total engines = 11 Total games = 55 Total rounds = 11 Total boards = 5 Total cycles = 1000000 draw rate (equal strength) = 64.0% White advantage = 30.0 rating[0]=3200 rating[1]=3100 rating[2]=3050 rating[3]=3000 rating[4]=2950 rating[5]=2900 rating[6]=2700 rating[7]=2700 rating[8]=2200 rating[9]=2200 rating[10]=2200 won = 586411 shared = 186268 loss = 227321 total = 1000000 won outright % = 58.6 <=============== won shared % = 18.6
One of the limitations of Ordo (and any other rating software for that matter) is that the draw rate (between equal opponents) is assumed constant throughout the rating spectrum, and this is not true. So, an average needs to be used (the model will be improved when I work with the wilo model).
Here are several combinations (reversed colors, #2 plays white against #1)
draw rate (equal strength) = 56.0%
White advantage = 30.0
won = 564497
shared = 179396
loss = 256107
total = 1000000
won outright % = 56.4
won shared % = 17.9
draw rate (equal strength) = 50.0%
White advantage = 30.0
won = 548826
shared = 173783
loss = 277391
total = 1000000
won outright % = 54.9
won shared % = 17.4
draw rate (equal strength) = 40.0%
White advantage = 30.0
won = 524417
shared = 164144
loss = 311439
total = 1000000
won outright % = 52.4
won shared % = 16.4
Then, in case of ties, I used random assignment of places, say 2 engines are tied, one engine has 50% of a win in that run, 50% the other. Didn't use colors.

Re: ICGA's 2015 World Computer Chess Championship/Events
I have some books of January, maybe we shouldn't jump to conclusions easily. I used 3 books from January, PlaychessNightmare (PN), a newer 1337 ChessPro (1337), King Asad Vipre 4 (KA), and a book from December, Rising Star (RS). The results are mixed, with PN coming on top. You can see individual results too.APassionForCriminalJustic wrote:Thank you Kai.

Re: ICGA's 2015 World Computer Chess Championship/Events
Thank you Kai for all of this fantastic information. I am using BookX.bin now as it is very strong according to Bookwars rating lists from January. It has already brought me great success in my matches.Laskos wrote:I have some books of January, maybe we shouldn't jump to conclusions easily.

Re: ICGA's 2015 World Computer Chess Championship/Events
anyway, it would be very nice to see any of the TOP 10 Engines in this Event.
Clearly Komodo and Stockfish will be favorites but i think if Junior has a 2 times faster HW and good book which leads to typical Junior like positions, Junior can beat Stockfish and Komodo in a single game and decide the Event with this game....
so i hope sf or ko will participate and give the audience amazing games...

Andi

Re: ICGA's 2015 World Computer Chess Championship/Events
It would just be a complete blowout. SF will probably never participate, so it really doesn't matter to speculate. Deep Junior is far too weak. Twice the hardware won't do anything. And openings aren't that difficult to deal with... it would just be a complete blowout; everybody knows this.Alibaba wrote:anyway, it would be very nice to see any of the TOP 10 Engines in this Event.

You seem to not have a feel about Elo differences. Games 1' + 1'', Texel on 4 cores and using PlaychessNightmare.ctg book.

Re: ICGA's 2015 World Computer Chess Championship/Events
Texel is stronger than Deep Junior, at least the latest version... SF will never enter with one core... 16+ will win the tournament... a 64 core deep junior for instance would not be scary... and scaling with more cores always gets worse... one core engines men nothing...
