Given a simple polygon P with n vertices and a starting point s on its boundary, the watchman route problem asks for a shortest route in P through s such that each point in the interior of the polygon can be seen from at least one point along the route. In this paper, we present a simple, linear-tim
In a recent paper Chekuri and Khanna improved the analysis of the greedy algorithm for the edge disjoint paths problem and proved the same bounds also for the related uniform capacity unsplittable flow problem. Here we show that their ideas can be used to get the same approximation ratio even for th
This article describes a heuristic and two exact algorithms for several classes of vehicle routing problems defined on tree networks. These include capacitated and time-constrained vehicle routing problems. One of the exact algorithms is based on the computation of bin packing lower bounds. The othe
