Computational algorithms are described which provide for constructing the set of associated edgeweighted directed graphs such that the average of the characteristic polynomials of the edge-weighted graphs gives the matching polynomial of the parent graph. The weights were chosen to be unities or pur
## Abstract We examine some properties of the 2βvariable greedoid polynomial __f__(__GΒ·,t,z__) when __G__ is the branching greedoid associated to a rooted graph or a rooted directed graph. For rooted digraphs, we show a factoring property of __f__(__GΒ·,t,z__) determines whether or not the rooted di
