....is stable, meaning that no group of agents has interest to change it. From the plethora of approximation algorithms for facility location we mention only the primal dual 3 approximation algorithm of Jain and Vazirani [20] and the currently best, 1. 52 approximation algorithm of Mahdian et al. [26]. The first constant factor approximation algorithm for the Single Source Rent or Buy Network Design problem is due to Karger and Minkoff [23] and Guha, Meyerson and Munagala [16] see also [17] Both algorithms use a variant of facility location to gather the clients, and then build a Steiner ....
