Let G be an embedded planar graph whose edges may be curves. The detour between two points, p and q (on edges or vertices) of G, is the ratio between the shortest path in G between...

— We present an O(n log1+ε n)-time algorithm for computing the optimal robot motion that maintains lineof-sight visibility between a target moving inside a polygon with n vertic...
Abstract-- In this paper we study the computational complexity and effectiveness of a concept we term "N-hub ShortestPath Routing" in IP networks. N-hub Shortest-Path Rou...
— A central problem of applications dealing with virtual environments is planning a collision-free path for a character. Since environments and their characters are growing more ...
Abstract-Dynamic routing protocols such as RIP and OSPF essentially implement distributed algorithms for solving the Shortest Paths Problem. The Border Gateway Protocol (BGP) is cu...
