In this paper, we study the minimum cost arborescence problem in a directed graph from the viewpoint of robustness of the optimal objective value. More precisely, we characterize an input graph in which the optimal objective value does not change even if we remove several arcs. Our characterizations lead to efficient algorithms for checking robustness of an input graph.
