We give a deterministic m^1+o(1) time algorithm that computes exact maximum flows and minimum-cost flows on directed graphs with m edges and polynomially bounded integral …
We present a deterministic (1+ o (1))-approximation O (n 1/2+ o (1)+ D 1+ o (1))-time algorithm for solving the single-source shortest paths problem on distributed weighted …
We give improved algorithms for the ℓp-regression problem, min x‖ x‖ p such that Ax= b, for all p∊(1, 2)∪(2,∞). Our algorithms obtain a high accuracy solution in iterations, where …

This paper introduces the concept of low-congestion shortcuts for (near-) planar networks, and demonstrates their power by using them to obtain near-optimal distributed algorithms for …
Many distributed optimization algorithms achieve existentially-optimal running times, meaning that there exists some pathological worst-case topology on which no algorithm can …
We present a general framework of designing efficient dynamic approximate algorithms for optimization problems on undirected graphs. In particular, we develop a technique that …

We devise new algorithms for the single-source shortest paths (SSSP) problem with non- negative edge weights in the CONGEST model of distributed computing. While close-to …
We provide universally-optimal distributed graph algorithms for (1+∊)-approximate shortest path problems including shortest-path-tree and transshipment. The universal optimality of …
In the distributed all-pairs shortest paths problem (APSP), every node in the weighted undirected distributed network (the CONGEST model) needs to know the distance from …
