Subject: Player program

Good Evening, Dave,

I have started trying to understand your Player program so that
I can read the result files myself in a somewhat different way.
I compiled the Unix version as a windows (Visual C++) program
after making some rather minor changes to keep the compiler happy.

I put in a position like this:

+ +-+ +

+ + + +
| 
+ + + +

+ + + +

Thinking I would get a symmetry (mirror about
diagonal top-left to bottom-right) and it appears
that your program fails to see the symmetry because
a 'minus' is not 'equal' to a 'vertical-bar'.

Perhaps all 'minus' and 'vertical-bar' could be
changed (early on) to some common, non-blank symbol.

Again, this is as far as I have looked into the
program and I may not even understand the purpose
of this symetery search.

Paul

Thanks for the note about the bug.  The purpose of the symmetry
check is to reduce the disk and memory space needed to store the
analysis.  Fortunately, the code does work on an empty square
board such as the 4x4 game.
