Shortest Vertex-Disjoint Two-Face Paths in Planar Graphs
[article]
2008
arXiv
pre-print
Let G be a directed planar graph of complexity n, each arc having a nonnegative length. Let s and t be two distinct faces of G; let s_1,...,s_k be vertices incident with s; let t_1,...,t_k be vertices incident with t. We give an algorithm to compute k pairwise vertex-disjoint paths connecting the pairs (s_i,t_i) in G, with minimal total length, in O(kn n) time.
