Abstract

We describe two widely used methods for the design and analysis of approximation algorithms, the primal-dual schema and the local ratio technique. We focus on the creation of both methods by revisiting two results by Bar-Yehuda and Even-the linear time primal-dual approximation algorithm for set cover, and its local ratio interpretation. We also follow the evolution of the two methods by discussing more recent studies.
