Abstract

This paper presents a fast algorithm for solving the n-queens problem. The basic idea is that many cases can be solved using pre-computed solutions, while the remaining cases are solved by calling the Sosic algorithm [1]. The novelty of the paper is in the observation that these precomputable cases exhibit a modular nature, i.e. they can be applied to 3/4 of the cases. The speedup for these cases is about 10 times faster than those solved using Sosic algorithm.
