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.

Hello Thomas,

Djinn is weak, but I know I haven't copied it--that said, I would be very curious who it is most similar to. Could you include it in the test, (latest public version is 0.992)?

thanks,

So Gaviota is a clone of Chiron ? I KNEW IT !!!

Hello Tom,
unfortunately Djinn supports only the Winboard protocol and Don's Similarity Tester works with UCI engines. I might try Wb2UCI, but I had some problems with it in the past.

LOL perhaps I said too soon that everyone can read a dendogram nowadays

You can safely ignore anything above 15 (perhaps also above 12.5).

Hi Thomas,

I think I need to do what Jon did with Arasan and make it support both UCI and Winboard. It isn't all that hard to do, I've just been too lazy. Maybe over Christmas.

does it means that Vajolet is not similar to any other engine?
I'm really happy about that

Santa said you'll receive a toy

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

Djinn 0.925x was included in the similarity testing that I did a couple of years ago. Ed is hosting my report here. In the dendrograms at that link, distances greater than 0.44 are good.
