31 Shortest Paths and Networks
We survey various forms of the problem, primarily in two and three dimensions, for motion of a single point, since most results have focused on these cases. We discuss shortest paths in a simple polygon (Section 31.1), shortest paths among obstacles (Section 31.2), and other metrics for length (Section 31.3). We also survey other related geometric network optimization problems (Section 31.4). H...
متن کاملA New Algorithm for the Discrete Shortest Path Problem in a Network Based on Ideal Fuzzy Sets
A shortest path problem is a practical issue in networks for real-world situations. This paper addresses the fuzzy shortest path (FSP) problem to obtain the best fuzzy path among fuzzy paths sets. For this purpose, a new efficient algorithm is introduced based on a new definition of ideal fuzzy sets (IFSs) in order to determine the fuzzy shortest path. Moreover, this algorithm is developed for ...
متن کاملConversion of Network Problem with Transfer Nodes, and Condition of Supplying the Demand of any Sink from the Particular Source to the Transportation Problem
In this article we present an algorithm for converting a network problem with several sources and several sinks including several transfer nodes and condition of supplying the demand of any sink from a particular source to the transportation problem. Towards this end, and considering the very special structure of transportation algorithm, after implementing the shortest path algorithm or ...
متن کاملAn Embedded Connectionist Approach for the Inverse Shortest Paths Problem
The Inverse Shortest Path (ISP) problem has recently been considered for applications involving the precise determination of unknown path costs, given only limited experts' knowledge of some shortest paths. Unlike previous approaches which are usually restrictive (such as the minimum change requirement) and algorithmically complicated, a more general but simple optimization scheme based on embe...
متن کاملModeling the 0-1 Knapsack Problem in Cargo Flow Adjustment
China’s railway network is one of the largest railway networks in the world. By the end of 2016, the total length of railway in operation reached 124,000 km and the annual freight volume exceeded 3.3 billion tons. However, the structure of network does not completely match transportation demand, i.e., there still exist a few bottlenecks in the network, which forces some freight flows to travel ...
