摘要
In this paper we study the problem of reconstructing a bicolored domino tiling of a rectangular surface from its horizontal and vertical projections. We use a reduction from the NP-complete problem NUMERICAL MATCHING WITH TARGET Sums in order to prove that, unless P = NP, this task cannot be performed in polynomial time. The reconstruction of monochromatic domino tilings is still open. (C) 2004 Elsevier B.V. All rights reserved.
