Re: computer-go: Second Order Liberties



Many Faces does not use the concept of 2nd or higher order liberties.

Many programs use higher-order liberties as a measure of how surrounded
a group is.  I prefer to use influence, measuring if there is a path to
another strong group.

I would like to add the notion of second order liberties to my program.  I
noticed in the GnuGo 2.6 documentation (Guys, you should make the current
docs availible on the web somewhere) that second order liberties cannot
exist on an opponent first order liberty.  Is this the way everyone does it?
What is the reasoning behind this?
