Light-Bot Boards
This is a directory of all of the boards available. The first twelve boards are the 12 levels of the original Light-Bot game, and the rest of them I made myself. For each board, there are links to open the board in the interactive applet (which you can use to either try to solve it yourself, or to run a genetic algorithm in your browser to search for a solution), to open the board in the board-editor (which will allow you to open your custom board in the interactive applet), or to jump to the results for that board in the gallery. All of the boards listed here have been solved by the genetic algorithm, so there are results for each one in the gallery.

This is the first level from the original game. Since it only has one target, the genetic algorithm isn't effective, and solutions can only be found by pure chance.

This is the tenth level from the original game. Of the 12 levels, this is the only one that I personally never found a solution for. I hadn't seen levels 11 and 12 until the genetic algorithm solved level 10 for me.
