lights_out, a MATLAB code which sets up the "Lights Out" game and allows a user to try to solve it.
The Lights Out game is played on a rectangular board of squares, usually a 5x5 grid, each square containingr a light that may be on or off. Clicking the mouse on a light switches it from on to off and vice versa. However, when you switch a light, you also switch the lights to the immediate left, right, above and below.
You start the game with a randomly chosen configuration of lights and it's up to you to figure out how to get them all out.
The computer code and data files described and made available on this web page are distributed under the GNU LGPL license.
lights_out is available in a C version and a C++ version and a MATLAB version.
