Given your original description I'm not so sure if what you're doing should actually be called a nearest neighbor method. It may be more like a decision tree... This said, the curse of dimensionality is a general problem which can come up with all similarity/distance based approaches using finite

Hi, Jacques, 1. Is this a complete go engine? I have renamed the gnugo.exe file in the /exe directory and the program no longer works. If it is not an engine, what is it? This is simple metamachine program. Ver.1.0 includes mm_hybrid.cpp in GNU directory. This file is a modified program of

I just want to weigh in on C# here since someone asked about it earlier in this thread. I recently switched from C++ to C#. I was not an expert at utilization of the STL, but I made do. Moving to C# has increase the rate at which I can try new things by at least 10x. I wish I would have done

[computer-go] MC heuristics not working

I was able to replicate the success (and with more iterations, failure) of the all-as-first heuristic. But I have not been able to see an improvement when I prohibit multi-stone suicides (I always prohibit single-stone suicides). Forgive me, but I am only interested in your response if you have

I would say the two best things about C# are the IDE and the garbage collection. Perhaps Java has as-good or better in both regards. I don't know. I have never been a Java guy. I became familiar with the .NET platform due to my job. I think it is fair to say that I ported my C++ code. Some
