Memory-EfficientApproximationAlgorithmsfor MAX-K-CUTandCorrelationClustering

Neural Information Processing Systems

Largescale instances of SDPs, thus, present a memory bottleneck. In this paper, we develop simple polynomial-time Gaussian sampling-based algorithms for these twoproblems thatuseO(n+|E|)memory andnearly achievethebestexisting approximation guarantees.

Upper bound on the objective. The proof consists of three parts. Upper bound on the objective. Upper bound on outer iteration complexity. Finally, we compute an upper bound on the complexity of each iteration, i.e., inner iteration complexity, of Algorithm 1. Upper bound on inner iteration complexity. We now derive an upper bound on N .
