AbstractWe present an algorithm for computing a maximum agreement subtree of two unrooted evolutionary trees. It takes O(n1.5 log n) time for trees with unbounded degrees, matching the best known time complexity for the rooted case. Our algorithm allows the input trees to be mixed trees, i.e., trees that may contain directed and undirected edges at the same time. Our algorithm adopts a recursive strategy exploiting a technique called label compression. The backbone of this technique is an algorithm that computes the maximum weight matchings over many subgraphs of a bipartite graph as fast as it takes to compute a single matching. © 2000 Society for Industrial and Applied Mathematics.
