Network coding gaps for completion times of multiple unicasts

B Haeupler, D Wajc, G Zuzic - 2020 IEEE 61st Annual …, 2020 - ieeexplore.ieee.org
We study network coding gaps for the problem of makespan minimization of multiple
unicasts. In this problem distinct packets at different nodes in a network need to be delivered …

Sending perishable information: Coding improves delay-constrained throughput even for single unicast

CC Wang, M Chen - IEEE Transactions on Information Theory, 2016 - ieeexplore.ieee.org
This paper considers network communications under a hard timeliness constraint, where a
source node streams perishable information to a destination node over a directed acyclic …

Approximating multicut and the demand graph

C Chekuri, V Madan - Proceedings of the Twenty-Eighth Annual ACM-SIAM …, 2017 - SIAM
In the minimum Multicut problem, the input is an edge-weighted supply graph G=(V, E) and a
demand graph H=(V, F). Either G and H are directed (Dir-MülC) or both are undirected …

The two-unicast problem

S Kamath, V Anantharam, D Tse… - IEEE Transactions on …, 2016 - ieeexplore.ieee.org
We consider the communication capacity of wireline networks for a two-unicast traffic
pattern. The network has two sources and two destinations with each source communicating …

Simple and fast rounding algorithms for directed and node-weighted multiway cut

C Chekuri, V Madan - Proceedings of the twenty-seventh annual ACM-SIAM …, 2016 - SIAM
We study the multiway cut problem in directed graphs and one of its special cases, the node-
weighted multiway cut problem in undirected graphs. In Directed Multiway Cut (Dir-MC) the …

Tight network topology dependent bounds on rounds of communication

A Chattopadhyay, M Langberg, S Li, A Rudra - Proceedings of the Twenty …, 2017 - SIAM
We prove tight network topology dependent bounds on the round complexity of computing
well studied k-party functions such as set disjointness and element distinctness. Unlike the …

A tight-approximation for linear 3-cut

K Bérczi, K Chandrasekaran, T Király, V Madan - Proceedings of the Twenty …, 2018 - SIAM
We investigate the approximability of the linear 3-cut problem in directed graphs, which is
the simplest unsolved case of the linear k-cut problem. The input here is a directed graph …
