A note on a QPTAS for maximum weight triangulation of planar point sets

Abstract

We observe that the recent quasi-polynomial time approximation scheme (QPTAS) of Adamaszek and Wiese for the Maximum Weight Independent Set of Polygons problem, where polygons have at most a polylogarithmic number of vertices and nonnegative weights, yields:1.a QPTAS for the problem of finding, for a set S of n points in the plane, a planar straight-line graph (PSLG) whose vertices are the points in S and whose each interior face is a simple polygon with at most a polylogarithmic in n number of vertices such that the total weight of the inner faces is maximized, and in particular,2.a QPTAS for maximum weight triangulation of a planar point set.
