摘要
In this paper we consider the extension of the n-queens problem to the Mobius strip; that is, the problem of placing a maximum number of nonattacking queens on the m x n chessboard for which the left and right edges are twisted connected. We prove the existence of solutions for the m x n Mobius board for classes of m and n with density 25/48 in the set of all m x n Mobius boards, and show the impossibility of solutions for a set of m and n with density 1/16. We also have computed the total number of solutions for the m x m Mobius board for m from 1 to 16.
