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

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

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.velmarin wrote: Marco, do not follow this path.

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

Can you explain the graph?ThomasJMiller wrote: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.
I understand that movei is similiar to gnuchess5.50 or fruit2.1(not sure if to both of them or only to one of them) but I do not understand the meaning of the numbers in the graph(when I say similiar I mean relative to the difference of movei with other engines).
Note that I am not surprised if you find that movei is more similiar to fruit2.1 relative to other engines because in the latest movei's before I stopped developing it I added some evaluation terms based on ideas that I understood from fruit2.1's code.

There are three clear clusters
1) Heron, Stockfish 4, Amitis, SF DD, SF 2.3.1, SF 3
2) H4, Robodini, IH, Vitruvius, Robbolito, Fire, DSaros, Bouquet, Critter, Strelka 5.5, BlackMamba, Gull2.3
3) Naum4.2, Strelka2, Murka3, Fruit2.1, Fruit2.2.1, D Onno, Hamsters, Alaric, colossus
There are 4-5 engines that require a closer analysis that cannot be extracted from what we see. The rest seems to be very unclear, or not related at all.
The farther to the right is the branch point, the less significant is the relationship of the leaves. But you cannot know from this only where to draw a line of "significance".

Re: TM Dendogram - Christmas 2013 Edition
If you look at only this, the less similar to the rest seems to be Deep Sjeng, Gaviota, Vajolet, (in that order) and then Shredder and Zappa.Marek Soszynski wrote:So, the most independent-minded (so to speak) engine of all those tested is Shredder, which hasn't been updated for years.ThomasJMiller wrote:Everyone can nowadays read a dendogram, so you can draw your own conclusions by yourself.
But the difference is all noise.
