Generalized Planar Matching.
Abstract
This paper proves that maximum planar H-matching (the problem of determining the maximum number of node-disjoint copies of the fixed graph H contained in a variable planar graph G) is NP-complete for any connected planar graph H with three or more nodes. It is also shown that perfect planar H-matching is NP-complete for any connected outerplanar graph H with three or more nodes, and is, somewhat surprisingly solvable in linear time for traingulated H with four or more nodes. The results generalize and unify several special-case results proved in the literature. The techniques can also be applied to solve a variety of problems, including the optimal tile salvage problem from wafer-scale integration. Although the authors prove that the optimal tile salvage problem and others like it are NP-complete, they also describe provably good approximation algorithms that are suitable for practical applications.
