The main result of this paper is that finding a heaviest triangle in a vertex-weighted graph on n vertices can be done in the same asymptotic time as finding any triangle. The best algorithm currently known for the latter problem needs time O(n2.376), which is the time needed by the best known algorithm for multiplying two n x n - matrices. The proof of this result is surprisingly elementary, even more so considering that no subcubic algorithm for this problem was known until STOC 2006.
