Abstract
The spider covering framework was originally proposed by Klein and Ravi (1993) in their attempt to design a tight approximation algorithm for the node-weighted network design problem. In this framework, an algorithm constructs a solution by repeatedly choosing a low-density graph. The analysis based on this framework basically follows from the idea used in the analysis of the well-known greedy algorithm for the set cover problem. After Klein and Ravi, the framework has been sophisticated in a series of studies, and efficient approximation algorithms for numerous network design problems have been proposed. In this article, we survey these studies on the spider covering framework.
