LaserTank is NP-complete

Computational Complexity 2020-04-21 v1 Combinatorics

Abstract

We show that the classical game LaserTank is NP\mathrm{NP}-complete, even when the tank movement is restricted to a single column and the only blocks appearing on the board are mirrors and solid blocks. We show this by reducing 33-SAT instances to LaserTank puzzles.
