Faster subtree isomorphism
We study the subtree isomorphism problem: Given trees H and G, find a subtree of G which is isomorphic to H or decide that there is no

Approximating the Maximum Isomorphic Agreement Subtree Is Hard
The Maximum Isomorphic Agreement Subtree (MIT) problem is one of the simplest versions of the Maximum Interval Weight Agreement Subtree method (MIWT) which is used to compare phyl...

Polynomial-Time Algorithms for the Ordered Maximum Agreement Subtree Problem
For a set of rooted, unordered, distinctly leaf-labeled trees, the NP-hard maximum agreement subtree problem (MAST) asks for a tree contained (up to isomorphism or homeomorphism) i...

An O(n log n) Algorithm for the Maximum Agreement Subtree Problem for Binary Trees
The Maximum Agreement Subtree problem is the following: given two rooted trees whose leaves are drawn from the same set of items (e.g., species), find the largest subset of these i...
