Abstract

Givenk rooted binary treesA1, A2, ..., Ak, with labeled leaves, we generateC, a unique system of lineage constraints on common ancestors. We then present an algorithm for constructing the set of rooted binary treesB, compatible with all ofA1, A2, ..., Ak. The running time to obtain one such supertree isO(k2 n2), wheren is the number of distinct leaves in all of the treesA1, A2, ..., Ak.
