Mechanism Design for Fractional Scheduling on Unrelated Machines
In this paper, we consider the mechanism design version of the fractional variant of the scheduling problem on unrelated machines. We give a lower bound of 2 − 1/n for any fracti...

Greedy and Heuristic Algorithms for Codes and Colorings
Abstract— Many of the fundamental coding problems can be represented as graph problems. These problems are often intrinsically difficult and unsolved even if the code length is ...

Improved Bounds for Online Routing and Packing Via a Primal-Dual Approach
In this work we study a wide range of online and offline routing and packing problems with various objectives. We provide a unified approach, based on a clean primal-dual method...

Choice Coordination with Multiple Alternatives (Preliminary Version)
Abstract. The Choice Coordination Problem with k alternatives (kCCP) was introduced by Rabin in 1982 [Rab82]. The goal is to design a wait-free protocol for n asynchronous processe...
