SYNOPSIS

9       queens [--display host:display.screen] [--window] [--root] [--window-id

DESCRIPTION

14       The queens program solves the n-queens problem (where, in this program,
15       N is between 5 and 10 queens) using a straightforward backtracking  al‐
16       gorithm.   The  problem is: how may one place N queens on an NxN chess‐
17       board such that no queen can attack a sister?
18

BUGS

53       It's not unknown for this and other OpenGL hacks to fail under hardware
54       accelaration (UtahGLX) and take the X server with them.  Texture images
55       must be 16x16 or 32x32 or 64x64 etc.
