This paper presents an optimal dynamic programming algorithm, the first such algorithm in the literature to solve the shortest path problem with time windows and additional linear costs on the node service start times. To optimally solve this problem, we propose a new dynamic programming algorithm w

We study a new version of the shortest path problem. Let G Γ (V, E) be a directed graph. Each arc e β E has two numbers attached to it: a transit time b(e, u) and a cost c(e, u), which are functions of the departure time u at the beginning vertex of the arc. Moreover, postponement of departure (i.e.
In this paper, we study the following all-pair shortest path query problem: Given the interval model of an unweighted interval graph of n vertices, build a data structure such that each query on the shortest path (or its length) between any pair of vertices of the graph can be processed efficiently
