A note on the random greedy triangle-packing algorithm

Abstract

The random greedy algorithm for constructing a large partial Steiner-Triple-System is defined as follows. We begin with a complete graph on nn vertices and proceed to remove the edges of triangles one at a time, where each triangle removed is chosen uniformly at random from the collection of all remaining triangles. This stochastic process terminates once it arrives at a triangle-free graph. In this note we show that with high probability the number of edges in the final graph is at most O(n7/4log5/4n) O\big( n^{7/4}\log^{5/4}n \big) .
