Approximation Algorithms for Single-minded Envy-free Profit-maximization Problems with Limited Supply
We present the first polynomial-time approximation algorithms for single-minded envy-free profit-maximization problems [13] with limited supply. Our algorithms return a pricing sc...

Improved Approximation of the Stable Marriage Problem
The stable marriage problem has recently been studied in its general setting, where both ties and incomplete lists are allowed. It is NP-hard to find a stable matching of maximum ...

An approximation algorithm for network design problems with downwards-monotone demand functions
Building on an existing 2-approximate algorithm for the class of network design problems with downwards-monotone demand functions, many of which are NP-hard, we present an algorith...
