Please correct me if I am wrong, but didn't the author of the sim test say that sim test results
less than 60 don't prove anything ?
Yes..with pleasure I will correct that you are wrong ))
Twinfish (100% clone of Stockfish) is clear proof that any engine can be released below than 60 % similarity
Plus I use time: 100 ms scale: 1.0, I mean the similarity is lower than Pia's calculation method
Otherwise...(with Pia's method) Naum will pass 60 % close to Rybka
To be honest,
I think Don's tool is just great...and I am very happy of using it !!
And it's disaster for those...who are copiers ! it detects almost perfectly !!!
It's true that some guys are managed to hack it...
But however, overall...its working just fine...it detects many clones etc...
Even Don's tool is better in detection than many chess engine experts !
For example (by the experts),
Ippolit can not be proven 100% as clone of a Rybka engine
or
Naum is derivative of Fruit
But in reality,
Naum is Rybka derivative (not Fruit derivative, experts should change their minds)))!!
Note also that the sim test tool helps us a lot !!!
As we see.... Ippolit is approx. 60% similar to Rybka 3
Even the first IPPO become on the scene after Rybka 3 release
Even the first IPPO Elo points were near to Rybka 3
I can give you more facts...just let me know...
In other words,
We should be very naive to not see that...
Btw, there is a good saying about this issue:
“It is well for the heart to be naive and for the mind not to be”
