Rybka on 1 cpu has lost in multiple tests/time controls to Robbolito

http://www.chesslogik.com/robbolito.htm

On multicore it loses to Igorrit 0.086v7

 Anywone interested in computer engine vs engine matches will find this fascinating.  ..

Iggorit/Robbolito with SCID  is a great  free alternative to Chessbase/deep Rybka/Aquarium.

Is anyone here interested in engine vs engine matches?

sounds very interesting

I heard this engine was a rykba clone.

Define clone.

Maybe ...but how is it stronger? And I have seen only a few similarities with rybka ...The blind bishop bug, and the "show mate" bug are fixed... fyi rybka does not show all the moves leading to  mate .,.

I think it probably did originate from decompiled sources but the modifications might  be enough to make that a moot point.

According to this website: http://www.chesslogik.com/robbolito.htm the programmers reverse engineered Rybka, but seeing as they provide both binary and source code downloads they must've written their own engine from scratch (i.e they did not just dissassemble the Rybka binary and start modifying it).

So what makes these two engines (Rybka and Robbolito or whatever it is called) clones of eachother when any two other chess engines that

1. Do not share the same source code

2. Are not equally strong

are clearly not clones?

Anyway I think it is cool how strong engines one can 'make on his own' if you just know some programming. I will definately keep an eye on this 'robbolito' engine :)

If you look at my original post I added that they already have multi-cpu support.

It is being actively tested... if you look

http://immortal223.borda.ru/?1-17-0-00000224-000-340-0

w32 version: rapidshare.de/files/48982733/Igorrit_0086v7_w32.exe.html 

x64 version: rapidshare.de/files/48982758/Igorrit_0086v7_x64.exe.html

I'm currently running the w32 version against rybka 3 ponder off 1m+6 seconds (a much longer tc then what most are testing with) and it is ahead by +32 elo so far.

And people only knew about it recently ...It has been in development for quite a while. 

You also seem to imply that they are hackers and not programmers ...thats odd because only very good programmers can rev. eng a product and then improve on it. (which is what Vas from rybka has said they did without providing any proof)

This is all supposition until its playing power can be proved in actual competition. I'll wait for these lists to change before I believe the author's (likely biased) assertion that this engine is a 3300 and the strongest in the world:

The Robbolito source code is available. It doesn't look like decompiled source -- in fact, it's full of comments. In Italian. There is no reason to think that it contains any copied chunks at all.

If you charge someone with a crime you have to provide proof. If the code is already out there, what can you lose by showing parts of the code that is already stolen that is identical?  Hell, any experienced programmer can do that without giving away any secrets the "thieves" didnt get.

You apparently know nothing of programming. You think its easy to  just rev eng an engine and make it +60elo in blitz?

I showed that they have multi-cpu because you claimed otherwise:

>>You come up with the "strongest engine in the world," beating hardcore professional work at the highest level the computer chess scene has ever witnessed that has been going on for years in just a couple of weeks and just can't add multi processor sport, or even book sport? Seriously. >>

My point is even if someone can prove that it is rev. eng.. - the programmers still came up with an innovation from a chess programming point of view.

But make no mistake these are a group of very talented programmers.

the engine has dethroned rybka.. not "on par" with rybka. 

Vas himself can be a cloner.   Programmer generally do this sort of thing a lot. Reliable experts have already charged Rybka for having stealing from open source fruit...(Since it is bound by GPL you cannot steal its code and make a profit )

A competing company could have done the same thing not released the source and no one would say anything.

Chess ratings list will eventually include this engine when it becomes apparant that Vas will never back up his accusation.

You have not defined what a clone is..

1. Rybka still loses in slow time control -20-32 elo ...faster time controls as much as -100 elo.

2. Its not a clone then. Rybka is not "genuine" then.  Parts of fruit code were lifted.

3. seriously -- you are the spammer -

Rybka PWNs all

+63 Elo for  this time control  1min 6 second increment is just a tad slower than the 40/4 control used in ccrl.

 hello all ...i have been following this in almost every chess forum about this rybka and robbo and its seems the world has divided into two some belives robbo is a clone of rybka some say not ..capatalist ,socialist lots of stuff ......

i too have downloaded almost every version of robbo and did played against rybka and rybka and robbo has almost same strength or may be a bit weaker rybka 3...the question of clone arises now when rybka 3 lost to robbo and simply bcoz its an open source made available free to every one.......

i have some question for rybka 3 owner and robbo owner

rybka 3

when rybka 3 is evolved mr programmer must have impoved it or evolved it with some underlying knowledge available for building this chess engine and the chess engine history is long before rybka has developed...so  if some one uses some underlying knowledge and developed something or improve something with that that cannot be simply called clone ...after all rybka 3 owner dos not invented or discovered something which people dont know infact he make some improvement ,some development he too have studied earlier module for chess engine available before making this rybka 3 ....

2..The credit should be given to the one who has made the first computer chess engine whether it be below 1000 ELO the revolution or invention begna then its all afterward people evolve make development and bring this ELO to 3200..

afterall rybka 3 is not an inevntion discovery its been a result of development only so mr programmer behaved that no one can defeat rybka3 and if anyone so he should hv made a clone of it ...before rybka 3 there r lots of engine available and his ealer version may be a clone of any  one who knows but development is always appreciated whether it be rybka or robbo...

3. his frustartion is viable of the fact that he losing some monetary as rybka 3 is not open source ...sorry mr programmer....

For robboooo 

1. Grt work done in bringing this robbo engine but one should also think that they also developed it bcoz there is a rybka 3 with ELO 3150 inspired to develop strongest engine for open source due credit is given to rybka 3 by robbo team as it inspired them to develop even strong and it may be that they too hv studied rybka 3 module .........

2. this is not a fight against capatalist or socialist ...its for the better of the game one should think this way.........

well with all this word i must thank  robbolito team for making this available to all and the people and game will be benefited with this and help the GAME TO REACH EVERY HOME AND NOT FOR MONEY BUT FOR GAME.

A clone cannot be much faster or defeat another clone there must be some improvement in chess engine that should be noted and it should be appreciated by all as they r not making money of it but for the game and people at large

rybka 3 should not feel humiliated as the world is not ended here they should try and develop new rybka 4 or 5 best luck to them ..and best of luck to robbo....

Certaily the revolution of chess engine has began and we all wanna eager to see where it ends .......

 thanks for both the team

best wishes
