[computer-go] Grid Cosmos

Hi, Jacques,

This is simple metamachine program.
Ver.1.0 includes mm_hybrid.cpp in GNU directory.
This file is a modified program of metamachine.c of GNU Go.
The program uses gnugo.exe as GTP engine.

Ver.1.01 Ver.1.02 include Game_Engine.cs (C# program) in
Grid_Cosmos/Main_Lib directory.
This file is a ported program of mm_hybrid.cpp (multi-thread version).

yes Tree_Set is pattern library.
I used about 34,000 games to make Tree_Set.
The dictionary-making program is Grid_Cosmos/Batch_Process.
Now I'm submitting a paper to AAAI-07.
If the paper would be accepted, I can open the detailed description of
pattern recognition algorithm in the conference.

> 3. How strong is your program?

Japanese researchers evaluated Grid Cosmos Ver.1.02.
The strength is between top commercial program and GNU Go 3.6.
(top commercial program >> Grid Cosmos > GNU Go)

However, the routine is very simple, as I wrote above.
So we could boost the strength by introducing good reading algorithm.

In Grid_Cosmos, we owe gnugo.exe for Go engine and
we require high speed only for pattern search. (file seek dll is written by C++)
For writing code and debugging, I like C# and I'm also satisfied with the speed.
