Re: ENGINE SPEED AND STRONG

My guess is that wilo is invariant with time only when you have two very similar versions of the same engine playing each other, when you have two totally different engines playing each other this won't be the case. ML solely based on win/los ratio derived by self-play does not seem optimal either,...

Re: ENGINE SPEED AND STRONG

I never dealt with a game with a very high draw rate like draughts before, it is possible that engines like Kingsrow and Scan are already near or at the highest level reachable. On the other hand I think that you can encode only a small subset of draughts knowledge in the 4x4 patterns that are curr...

Re: ENGINE SPEED AND STRONG

Hi, Playing 'swindle' moves to avoid dead draws against a weaker opponent might work indeed, even against GMI, but it is not a good idea to play these type of moves against other computer opponents because there is a very big chance they will out calculate you. I have an other approach, I want to h...

Re: ENGINE SPEED AND STRONG

Hi to all, For the fast games, i admit that it was with the "original" version of Scan, realeased and uploaded on Harm Jetten's site. So i don't knew that 0.5 minutes/75 wasn't allowed into dxp protocol. It was just for a test to see. Like Ed said, in 1min Scan take the upper. It's the another only ...

Re: ENGINE SPEED AND STRONG

Hi, Just added Ed's GAMEREQ_FISHER to DXP, now it is possible to run a game in a few seconds. 6 secs. per game is usable, when I make the times very small the GUI and the console window start taking their toll, minimizing the windows help but than it is not possible to follow the games. Kingsrow is...

Re: ENGINE SPEED AND STRONG

Hi Catherine, last night I couldn't resist to work somewhat more on the engine. I'm afraid that I'm addicted to work on it. I totally reworked the quiescence search (which is very sensitive to tuning) and I made the pruning more aggressive. With bullet-tests the Elo rating went up by about 25 point...

Re: ENGINE SPEED AND STRONG

Hi Taille It is true that egdb have a important function into the playing strenght of an engine. I think that the evaluation based on the goal to reach the max EGDB with optimals egdb moves to force opponent to do a mistake and win itsn't so bad. It must be the perfect "team" to have the perfect en...

Re: ENGINE SPEED AND STRONG

Hi Joost, I think that the engine crashed because of the cfg setting with the egdb path wich no matched. Now that i saw how it is, the engine run perfectly. It seem that the new engine is more stronger, wich all the fings you done and fixed. Thank again. Catherine Hi Catherine, last night I couldn'...

Re: ENGINE SPEED AND STRONG

Hi Taille, If a program have the 40 pieces egdb, i suppose that it contain win/draw /loss informations, so if the program see after a few moves an move error from his opponent, it will win. I think that almost GMI and/or best engine can't play without error until the 50 or 60 first moves. So if und...

Re: ENGINE SPEED AND STRONG

This question is for you and all the others programmers: What are the elements that can do the "perfect engine" this wich can for example will never lose. It's the hardware on what it's launched, search evaluation, speed of search? Thank to all Catherine. Oops what do you mean by "perfect engine". ...

Re: ENGINE SPEED AND STRONG

Hi Krzysztof, No, these are the weights for the pattern evaluation, I don't have a book yet. Besides gaining some time a book for draughts does not seem very important. Yesterday I started looking at the engine again because I wanted to improve the time-control and add a console mode to enable you ...

Re: ENGINE SPEED AND STRONG

Hi Joost. I have a question for you. In the folder with the engine is a file called argusv106 bin, I understand that this is a book debut.

Re: ENGINE SPEED AND STRONG

Hi Catherine, Well, it is up to you if you want to buy another computer, laptops are usually very slow. About my engine, I guess it is all very much the same as the other top-engines, it's only virtue is that it is faster, but not tuned as good as the others yet. I hope to get it stronger when it i...
