PPT-Bicriteria Rectilinear Shortest Paths among Rectilinear

Obstacles in the Plane Haitao Wang Utah State University SoCG 2017 Brisbane Australia The rectilinear minimumlink path problem Input a rectilinear domain P of n vertices and . Our algorithms output an implicit representation of these paths in a digraph with vertices and edges in time log We can also 731nd the shortest paths from a given source to each vertex in the graph in total time log kn We de scribe applications to F. n. = F. n-1. + F. n-2.
