Given an edge-weighted complete graphGon 3nvertices, the maximum-weight triangle packing problem asks for a collection ofnvertex-disjoint triangles inGsuch that the total weight of edges in thesentriangles is maximized. Although the problem has been extensively studied in the literature, it is surprising that prior to this work, no nontrivial approximation algorithm had been designed and analyzed for its metric case, where the edge weights in the input graph satisfy the triangle inequality. In this paper, we design the first nontrivial polynomial-time approximation algorithm for the maximum-weight metric triangle packing problem. Our algorithm is randomized and achieves an expected approximation ratio offor any constant.
