摘要:

监控应用需要一组异构车辆来访问一组目标。在这篇文章中,我们考虑了一个基本的路由问题,在这些应用中出现的涉及两辆车。具体来说,我们考虑一个路由问题,有两个不同的车辆,从不同的初始位置开始,和一组目标。目标是为每个车辆找到一个行程,使得每个目标至少被车辆访问一次,并且车辆行驶的距离之和最小。我们提出了一个原始-对偶算法,这个路由问题的一个变种,提供了一个近似比为2。

英文摘要:

Surveillance applications require a collection of heterogeneous vehicles to visit a set of targets. In this article, we consider a fundamental routing problem that arises in these applications involving two vehicles. Specifically, we consider a routing problem where there are two heterogeneous vehicles that start from distinct initial locations, and a set of targets. The objective is to find a tour for each vehicle such that each of the targets is visited at least once by a vehicle and the sum of the distances traveled by the vehicles is a minimum. We present a primal-dual algorithm for a variant of this routing problem that provides an approximation ratio of 2.
