We consider the communication complexity of finding an approximate maximum matching in a graph in a multi-party message-passing communication model. The maximum matching problem is one of the most fundamental graph combinatorial problems, with a variety of applications. The input to the problem is a graphGthat hasnvertices and the set of edges partitioned overksites, and an approximation ratio parameter. The output is required to be a matching inGthat has to be reported by one of the sites, whose size is at least factorof the size of a maximum matching inG. We show that the communication complexity of this problem isinformation bits. This bound is shown to be tight up to afactor, by constructing an algorithm, establishing its correctness, and an upper bound on the communication cost. The lower bound also applies to other graph combinatorial problems in the message-passing communication model, including max-flow and graph sparsification.
