Solving the light up with Ant Colony Optimization

A number of single-player games have been proven to be computationally difficult, including the Light Up. Although, recently, such single-player games have received considerable attention from the scientific community, only a few papers address the Light Up. This paper presents a two phase Ant Colony Optimization algorithm to solve this puzzle. In the first phase, logical rules are applied to the game grid in order to restrict the space searched by the algorithm in the second phase. The approach was applied to thirty-two game instances with grids ranging from 7×7 to 40×30 solving them efficiently.
