What is Shortest Path Problem

Chapter 31

The routing problem of finding the shortest—or least cost—path through a network.

Published in Chapter:

Routing

Kevin M. Curtin (George Mason University, USA)

Source Title: Handbook of Research on Geoinformatics

DOI: 10.4018/978-1-59140-995-3.ch031

Abstract

Routing is the act of selecting a course of travel. Routing problems are one of the most prominent and persistent problems in geoinformatics. This large research area has a strong theoretical foundation with ties to operations research and management science. There are a wide variety of routing models to fit many different application areas, including shortest path problems, vehicle routing problems, and the traveling salesman problem, among many others. There are also a range of optimal and heuristic solution procedures for solving instances of those problems. Research is ongoing to expand the types of routing problems that can be solved, and the environments within which they can be applied.
