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.

Level 1

  • Open in the interactive applet
  • Edit in the board-editor
  • View results for this board 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.

Level 2

  • Open in the interactive applet
  • Edit in the board-editor
  • View results for this board in the gallery

This is the second 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.

Level 3

  • Open in the interactive applet
  • Edit in the board-editor
  • View results for this board in the gallery

This is the third level from the original game.

Level 4

  • Open in the interactive applet
  • Edit in the board-editor
  • View results for this board in the gallery

This is the fourth 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.

Level 5

  • Open in the interactive applet
  • Edit in the board-editor
  • View results for this board in the gallery

This is the fifth 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.

Level 6

  • Open in the interactive applet
  • Edit in the board-editor
  • View results for this board in the gallery

This is the sixth level from the original game. It is the first level that requires the use of functions.

Level 7

  • Open in the interactive applet
  • Edit in the board-editor
  • View results for this board in the gallery

This is the seventh level from the original game.

Level 8

  • Open in the interactive applet
  • Edit in the board-editor
  • View results for this board in the gallery

This is the eighth level from the original game.

Level 9

  • Open in the interactive applet
  • Edit in the board-editor
  • View results for this board in the gallery

This is the ninth level from the original game.

Level 10

  • Open in the interactive applet
  • Edit in the board-editor
  • View results for this board in the gallery

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.

Precarious

  • Open in the interactive applet
  • Edit in the board-editor
  • View results for this board in the gallery

This board requires the robot to use jumping commands to follow the path, but is on a high ledge so that any jump in the wrong direction will trap it off of the ledge.

Level 11

  • Open in the interactive applet
  • Edit in the board-editor
  • View results for this board in the gallery

This is the eleventh level from the original game.

Level 12

  • Open in the interactive applet
  • Edit in the board-editor
  • View results for this board in the gallery

This is the twelfth and final level of the original game.

Plus

  • Open in the interactive applet
  • Edit in the board-editor
  • View results for this board in the gallery

This board is a simple experiment involving targets in four different directions.

Distraction

  • Open in the interactive applet
  • Edit in the board-editor
  • View results for this board in the gallery

This board is a test to see if the genetic algorithm can overcome the tendency to favor programs that immediately jump off of the shelf toward the 9 targets below, unable to light the last target.

Forest

  • Open in the interactive applet
  • Edit in the board-editor
  • View results for this board in the gallery

This board is a group of targets placed among a group of fixed pillars.

Forest 2

  • Open in the interactive applet
  • Edit in the board-editor
  • View results for this board in the gallery

This board takes the more regularly laid-out Forest board and moves the targets around in a less ordered way.

Halls 2

  • Edit in the board-editor
  • View results for this board in the gallery

Precarious 2

  • Open in the interactive applet
  • Edit in the board-editor
  • View results for this board in the gallery

This board has the same challenge as the first Precarious level, but with a longer and more arbitrary path to follow.

  • View results for this board in the gallery

This board presents the challenge of handling two sequences of targets which require different commands for movement (jumping and walking) but are otherwise identical.

Equis

  • Open in the interactive applet
  • Edit in the board-editor
  • View results for this board in the gallery

I made this board because I thought it might be a little interesting. No other reason.

Equis Dos

  • Open in the interactive applet
  • Edit in the board-editor
  • View results for this board in the gallery

This board is a modification to the original Equis board, featuring holes that make it considerably more challenging.

This board has a similar concept to the Plus board, that of forcing the robot to backtrack.

  • Edit in the board-editor
  • View results for this board in the gallery

This board features four different levels that the robot must visit in order, and each new level requires backing up before proceeding.
