Integrality Gap of the Vertex Cover Linear Programming Relaxation

Mohit Singh

We give a characterization result for the integrality gap of the natural linear programming relaxation for the vertex cover problem. We show that integrality gap of the standard li…

Online and Offline Greedy Algorithms for Routing with Switching Costs

Roy Schwartz, Mohit Singh, Sina Yazdanbod

Motivated by the use of high speed circuit switches in large scale data centers, we consider the problem of circuit switch scheduling. In this problem we are given demands between…

Sticky Brownian Rounding and its Applications to Constraint Satisfaction Problems

Sepehr Abbasi-Zadeh, Nikhil Bansal, Guru Guruganesh +3

Semidefinite programming is a powerful tool in the design and analysis of approximation algorithms for combinatorial optimization problems. In particular, the random hyperplane rou…
