queens - n queens screensaver
queens [-display host:display.screen] [-window] [-root] [-install]
[-visual visual] [-delay microseconds] [-fps]
The queens program solves the n-queens problem (where, in this program,
N is between 5 and 10 queens) using a straightforward backtracking
algorithm. The problem is: how may one place N queens on an NxN chess-
board such that no queen can attack a sister?
queens accepts the following options:
-window Draw on a newly-created window. This is the default.
-root Draw on the root window.
Install a private colormap for the window.
Specify which visual to use. Legal values are the name of a
visual class, or the id number (decimal or hex) of a specific
visual. -fps Display a running tally of how many frames per
second are being rendered. In conjunction with -delay 0, this
can be a useful benchmark of your GL performance.
DISPLAY to get the default host and display number.
to get the name of a resource file that overrides the global
resources stored in the RESOURCE_MANAGER property.
It's not unknown for this and other OpenGL hacks to fail under hardware
accelaration (UtahGLX) and take the X server with them. Texture images
must be 16x16 or 32x32 or 64x64 etc.
