Integrality ratio for group Steiner trees and directed steiner trees
The natural relaxation for the Group Steiner Tree problem, as well as for its generalization, the Directed Steiner Tree problem, is a flow-based linear programming relaxation. We...

Beyond the Flow Decomposition Barrier
We introduce a new approach to the maximum flow problem. This approach is based on assigning arc lengths based on the residual flow value and the residual arc capacities. Our appro...

Smooth Boosting for Margin-Based Ranking
We propose a new boosting algorithm for bipartite ranking problems. Our boosting algorithm, called SoftRankBoost, is a modification of RankBoost which maintains only smooth distri...

Branch Merge Reduction of RLCM Networks
— In this paper we consider the problem of finding a smaller RLCM circuit that approximately replicates the behavior (up to a certain frequency) of a given RLCM circuit. Targeted...
