Re: [computer-go] Positions illustrative of computer stupidity ?
I think it's all in the presentation. Even if they are not even beginners, with skill you can help them appreciate how some basic concepts are difficult for a computer. For instance, I think that you can teach the principle of 2 eyes with a very simple example perhaps involving just 1 point eyes. Then move to showing them that if the eyes are bigger, it starts getting ambiguous very quickly - and at some point it starts taking a relatively advanced player to discern when a bigger space is equivalent to an eye. You start just by showing them a group with 1 single point eye and how it gets captured. They you progress: what if there is another eye? etc. - Don On Wed, 2006-11-22 at 12:27 -0800, steve uurtamo wrote: i think that these won't be terribly easy for your audience to parse. part of the problem is that gnugo is actually better than a beginner, for instance. i'd say anything that isn't tactical in nature is a good example. moves that don't directly make any territory, but which threaten to, for instance. look at the first 8-10 moves of most any KGS game played by robert jasiek (sum) that ended in an early resignation. s.

Re: [computer-go] Positions illustrative of computer stupidity ?
The attached position requires some basic understanding of Go. But its in my experience a nasty problem. There is a simple rule for capture races. The side with the higher number of liberties wins (if there are no eyes and more =2 inside liberties involved). The side to move counts as a 1/2 liberty. Unfortunately this rule is not valid in the position. White is unconditionally dead. All liberties are equal, some are more equal.

Re: [computer-go] Positions illustrative of computer stupidity ?
Attached is another simple problem. A tactical-solver might work as this. It checks all strings. If the number of liberties is below a thresold (e.g. 3) it defines the string as a prey and tries to kill the string. Then the solver takes the next prey, tries to kill it. For this tactical solver the white stones are save. Each prey can escape individually, but due to the double-atari one of them is dead. This is a trivial example, but there are more difficult ones which are much harder to solve. Even the best strong programms like Handtalk are very vulnerable to double attacks (there are other ones like Many Faces which do not suffer from this problem)..
