Directed acyclic graphs have clear order, where precedence relations among vertices are naturally defined. Many directed real world networks contain inherent order that may be masked by strong connectivity components or long circles. Two algorithms aim at uncover the inherent order in directed networks that contain cycles as well. This package contains implementation of algorithms that handle the directionality problem. The two algorithms receive a binary directed graph and return a centrality score where high score vertices precede lower score vertices in the graph hierarchy. The flow algorithm exploits the asymmetry in distances in the directed graph and its underlying undirected graph. The hierarchy energy algorithm minimizes an energy function that takes into consideration all ordered relations of unidirectional edges.
