1 .TH XScreenSaver 1 "May 2002"
3 queens \- n queens screensaver
6 [\-display \fIhost:display.screen\fP]
10 [\-visual \fIvisual\fP]
11 [\-delay \fImicroseconds\fP]
15 The \fIqueens\fP program solves the n-queens problem (where, in this
16 program, N is between 5 and 10 queens) using a straightforward
17 backtracking algorithm. The problem is: how may one place N queens
18 on an NxN chessboard such that no queen can attack a sister?
21 accepts the following options:
24 Draw on a newly-created window. This is the default.
27 Draw on the root window.
30 Install a private colormap for the window.
32 .B \-visual \fIvisual\fP\fP
33 Specify which visual to use. Legal values are the name of a visual class,
34 or the id number (decimal or hex) of a specific visual.
37 Render in wireframe instead of solid.
39 Display a running tally of how many frames per second are being rendered.
40 In conjunction with \fB\-delay 0\fP, this can be a useful benchmark of
46 to get the default host and display number.
49 to get the name of a resource file that overrides the global resources
50 stored in the RESOURCE_MANAGER property.
52 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.
