Algorithmic Aspects of Tree Amalgamation
2000
Journal of Algorithms
The amalgamation of leaf-labelled trees into a single (super)tree that "displays" each of the input trees is an important problem in classification. We discuss various approaches to this problem and show that a simple and well known polynomial-time algorithm can be used to solve this problem whenever the input set of trees contains a minimum size subset that uniquely determines the supertree. Our results exploit a recently established combinatorial property concerning the structure of such
