## Abstract In this paper, we propose the problem of identifying a minimumβweight rooted notβnecessarilyβspanning arborescence (MRA) in a directed rooted acyclic graph with weights on arcs. We show this problem to be NPβhard and formulate it as a zeroβone integer program. We develop a heuristic __H
## Abstract The Minimum Arborescence problem (MAP) consists of finding a minimum cost arborescence in a directed graph. This problem is NPβHard and is a generalization of two wellβknown problems: the Minimum Spanning Arborescence Problem (MSAP) and the Directed Node Weighted Steiner Tree Problem (D
