Abstract

ABSTRACT Hitchhiking is a travel mode characterised by unpredictable travel times involving several possible combinations of lifts on roads. In this paper, we formulate a hitchhiker’s problem and develop a time-dependent stochastic route planning algorithm for hitchhikers. Namely, we introduce a concept of the stochastic time-dependent hitchhiking graph to find hitchhiking strategies with the least expected travel time or maximised reliability. We introduce various heuristics to prune the original hitchhiking graph to improve computational efficiency. We provide a complexity analysis of the problem and evaluate the proposed solution on real-world networks of several countries.

随机时变搭便车问题的最优路线规划

搭便车是一种旅行方式，其特征是不可预测的旅行时间，涉及道路上几种可能的电梯组合。本文提出了一个搭便车者问题，并提出了一个随时间变化的随机路线规划算法。也就是说，我们引入随机时间相关搭便车图的概念来寻找具有最小期望旅行时间或最大可靠性的搭便车策略。为了提高计算效率，我们引入了各种启发式方法对原始搭便车图进行剪枝。我们对该问题进行了复杂性分析，并在几个国家的实际网络中评估了提出的解决方案。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
