Hi

Maybe too late ... Nethertheless, i remember a funny thing.
Some time ago i implemented opponent good move is good for me in a GNU Go bot
and this gave funny things like reverse monkey jump.

David Doshay reported this too with early SlugGo (which also takes into
account opponent good moves)


XXXO

.a..   Instead of blocking the monkey jump, O plays in a :)


I m pretty sure no human player would think of this.

Re: [computer-go] Positions illustrative of computer stupidity ?

2006-12-03 Thread David Doshay

This is a good example of a reasonable heuristic leading to an
undesired solution after a correct evaluation. Most of the time
SlugGo did this it was correct that stopping the opponent's
monkey-jump was the biggest move on the board, so using
the heuristic was valuable. It just took things too far and chose
the exact same move for the fix.

We had to soften the heuristic to Moves near their best move
may be very good for me. Playing with the weights for near
cut down on the number of reverse monkey jumps.


Cheers,
David

[computer-go] language choices

2006-12-03 Thread Don Dailey
Since we have been talking about programming language recently, I was
curious as to whether anyone on this group has experimented with the
digital mars D programming language?

From the hype on the web page, it looks an extremely capable programming
language that is supposed to be fast native code compiled like C, but
have all the features you might ask for in a higher level language.  

It may be complete garbage for all I know,  but at least from the
description it seems like something I would be happy to use.It looks
like  a cleaned up version of C,  with a bunch of higher level language
features built right in such as associative arrays, garbage collection,
dynamic arrays,  oop, etc.It compiles to native code, has a GCC
compiler as well as a digital mars compiler.  

Since my go program is tiny, I may give it a try and do a speed
comparison.   But I was wondering if anyone else has had any experience
with it, good or bad.

A note: we're working on converting Orego back from C++ to Java, and  
we're getting 5,000 (totally random at this point) simulated games  
per second. We'll probably continue in this direction.
