TM Dendogram - Christmas 2013 Edition

[velmarin]

it's has been the most beautiful toy I received, I used lot's of ideas code from stockfish and other open source engines and I alway worried about "being a clone".
Now I'm happy. My engine is not strong but it's not a clone too

Marco, do not follow this path.

I indigestible theme clone.
Vajolet is a derivative by Winglet , educational engine by Stef Luijten.

Keep up the good work, but not entangled.
Greetings Jose.

Will programmers receive toys and candy or coal this Christmas? To find out, let's check Santa's Naughty or Nice List
Latest releases of many commercial and free engines have been included together with the most important open source ones.

Testing all the engines and preparing the dendogram has taken a lot of time so I wouldn't like this thread to be moved to the Engine Origins subforum. Therefore, please, avoid making comments like XXX is clone of YYY or so.
Everyone can nowadays read a dendogram, so you can draw your own conclusions by yourself.

Thanks to Adam Hair who helped me improve selfsimilarity results.

Protector 1.5.0 is most similar to Stockfish DD, yet Protector came out first. Therefore not much can be read into that, despite the correlation being less than the 12.5 cutoff mentioned?

In this dendrogram, Protector 1.5.0 is most similiar to the group of Stockfish engines, not necessarily Stockfish DD itself. If we could look at the similarity percentages for each pair, I believe that Protector 1.5.0 would be more similar to SF 2.3.1 than to SF DD.

The confidence of the branches cannot be assessed if a bootstrap analysis is not done. Quite likely, this protector similarity is meaningless.

Everyone can nowadays read a dendogram, so you can draw your own conclusions by yourself.

So, the most independent-minded (so to speak) engine of all those tested is Shredder, which hasn't been updated for years.

You are right Miguel. Unfortunately I'll be very busy till the end of the year. When possible I'll make some analysis of the data.

Nonetheless, results <= 5 are very interesting, we have VERY high percentages there (>70-80-90% ....while the average is about 49%).

all branches >= 15 are surely meaningless...

Nice tree Thomas. Did you use fixed time/move or fixed depth?
I have to admit that cheng cheats a bit as it uses 100msec less time in fixed time mode
Next version (if any) won't use this "feature" anymore.

Hi Jose I really don't understood what you mean.
??I indigestible theme clone.??

Vajolet is a derivative by Winglet , educational engine by Stef Luijten. I started studying Stef Luijten code, and some of his code is still here (magic bitboard code for example), then studied Fruit , Cheng, Stockfish. If you had read my code yuo'll see lot of of idea from stockfish.

Keep up the good work, but not entangled. what do you man by entangle? bluff , deceive, cheat? It's not my purpose.
I don'tknow what you mean by derivatve work. if you are talking about forking a project I don't think I have forked it. I started my project from scratch after playing around with winglet code for some time.

HEHE, from scratch, well, congratulations.
