A Linear Time Algorithm for Computing Max-Flow Vitality in Undirected Unweighted Planar Graphs

Giorgio Ausiello, Lorenzo Balzotti, Paolo G. Franciosa +2

The vitality of an edge in a graph with respect to the maximum flow between two fixed vertices and is defined as the reduction of the maximum flow value caused by the remov…

How Vulnerable is an Undirected Planar Graph with respect to Max Flow

Lorenzo Balzotti, Paolo G. Franciosa

We study the problem of computing the vitality of edges and vertices with respect to the -max flow in undirected planar graphs, where the vitality of an edge/vertex is the …

Non-Crossing Shortest Paths in Undirected Unweighted Planar Graphs in Linear Time

Lorenzo Balzotti, Paolo G. Franciosa

Given a set of well-formed terminal pairs on the external face of an undirected planar graph with unit edge weights, we give a linear-time algorithm for computing the union of non-…

Simpler and Unified Recognition Algorithm for Path Graphs and Directed Path Graphs

Lorenzo Balzotti

A path graph is the intersection graph of paths in a tree. A directed path graph is the intersection graph of paths in a directed tree. Even if path graphs and directed path graphs…

Computing Lengths of Non-Crossing Shortest Paths in Planar Graphs

Lorenzo Balzotti, Paolo G. Franciosa

Given a plane undirected graph with non-negative edge weights and a set of terminal pairs on the external face, it is shown in Takahashi et al. (Algorithmica, 16, 1996, pp.…
