Efficient Triangle Counting in Large Graphs via Degree-based Vertex Partitioning

Mihail N. Kolountzakis, Gary L. Miller, Richard Peng +1

The number of triangles is a computationally expensive graph statistic which is frequently used in complex network analysis (e.g., transitivity ratio), in various random graph mode…

Approximate Dynamic Programming using Halfspace Queries and Multiscale Monge decomposition

Gary L. Miller, Richard Peng, Russell Schwartz +1

Let $P = (P_{1}, P_{2}, \dots, P_{n})$ , $P_i \in \field{R}$ for all $i$ , be a signal and let $C$ be a constant. In this work our goal is to find a function $F:[n]\rightarrow \field{R}$ wh…

Approaching optimality for solving SDD systems

Ioannis Koutis, Gary L. Miller, Richard Peng

We present an algorithm that on input of an $n$ -vertex $m$ -edge weighted graph $G$ and a value $k$ , produces an {\em incremental sparsifier} $G^$ with $n - 1 + m / k$ edges, such…
