| Abstract: | Let G=(V,E) be a directed graph such that for some r in V, and for every u in V-{r}, there are k edge disjoint, directed paths from r to u. We present an O(k|V||E|+k^3|V|^2) algorithm to construct k edge disjoint branchings rooted at r. This algbrithm is a modification of an O(|k|^2|V||E|) algorithm of Shiloach for the same task which is based on Lovasz proqf of a Theotem of Edmonds, that implies the existence of such edge disjoint branchings. |
