Keywords: cophylogeny, heuristic, NP complete, parsimony, phylogenetic network, reconstruction.

We present a proof that shows that the general problem of reconciling evolutionary histories is NP-complete and provide a sharp boundary where this intractability begins. We also show that a related problem, that of finding Pareto optimal solutions, is NP-hard. As a byproduct of our results, we give a framework by which meta-heuristics can be applied to find good solutions to this problem. © Mary Ann Liebert, Inc. 2009." 2 Roderic D.M. Page and Michael A.
