  • In this paper, we study the weak point matching prob- lem for a given set of n points and a class of equilateral triangles. The problem is to find the maximum car- dinality matching of the points using equilateral trian- gles such that each triangle contains exactly two points and each point lies at most in one triangle. Under the non-degeneracy assumption, we present an O(n3/2) time algorithm using the TD-Delaunay graph and a graph matching algorithm. Also, we show that the lower bound for the number of matched points is b2n/3c which is optimal in the worst case.
