Memory-Efficient Approximation Algorithms for MAX-K-CUT and Correlation Clustering

Research output: Chapter in Book/Report/Conference proceedingConference PaperResearchpeer-review

Abstract

MAX-K-CUT and correlation clustering are fundamental graph partitioning problems. For a graph G = (V, E) with n vertices, the methods with the best approximation guarantees for MAX-K-CUT and the MAX-AGREE variant of correlation clustering involve solving SDPs with O(n2) constraints and variables. Large-scale instances of SDPs, thus, present a memory bottleneck. In this paper, we develop simple polynomial-time Gaussian sampling-based algorithms for these two problems that use O(n + |E|) memory and nearly achieve the best existing approximation guarantees. For dense graphs arriving in a stream, we eliminate the dependence on |E| in the storage complexity at the cost of a slightly worse approximation ratio by combining our approach with sparsification.
