Let G be an undirected plane graph with nonnegative edge length, and letkterminal pairs lie on two specified face boundaries. This paper presents an algorithm for findingk“noncrossing paths” inG, each connecting a terminal pair, and whose total length is minimum. Noncrossing paths may share common vertices or edges but do not cross each other in the plane. The algorithm runs in timeO(nlogn) wherenis the number of vertices inGandkis an arbitrary integer.
