board_toggle_matrix

A lightsout game can be solved using Gaussian elimination. A special matrix
<code>A</code> needs to be used to solve <code>Ax=b</code>, where <code>b</code> is the current
board configuration and <code>x</code> is the solution. This function returns
the matrix <code>A</code>.

Lights Out is a puzzle game consisting of a grid of lights
that are either on or off. Pressing any light will toggle it and its
adjacent lights. The goal of the game is to switch all the lights off. This
package provides an interface to play the game on different board sizes,
both through the command line or with a visual application. Puzzles can
also be solved using the automatic solver included. View a demo
