[computer-go] crazystone, mogo, go4++, greenpeep, valkyra or other strong programs on cgos19x19?

[David Fotland]

It's a bug.  If the move generator returns no moves at an internal node in
the main search, it passes.  Mogo keeps playing on after there are no points
left.  During the search after the forced response to mogo's move, there are
no moves generated.  I don’t allow a pass in an internal node, so the search
returns an error and it passes.  It will be fixed in the next version (along
with many other bugs).  The Alpha-beta code barely works.  You can see how
weak the first few buggy versions very if you look at gnugo's crosstable.

I hope it will get much stronger in the next few weeks as I wring out the
bugs.

It's nice to see Valkyria join.  Anyone else?
