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.
## Abstract In this article, we investigate two different recoverable robust (RR) models to deal with cost uncertainties in a shortest path problem. RR extends the classical concept of robustness to deal with uncertainties by incorporating limited recovery actions after the full data are revealed.
## Abstract We study the complexity of two inverse shortest paths (ISP) problems with integer arc lengths and the requirement for uniquely determined shortest paths. Given a collection of paths in a directed graph __D__ = (__V__, __A__), the task is to find positive integer arc lengths such that th
