About the Event

Authors Ami Paz and Gregory Schwartzman present a simple deterministic single-pass (2+eps )-approximation algorithm for the maximum weight matching problem in the semi-streaming model. This improves upon the currently best known approximation ratio of (3.5+eps ). Theirs algorithm uses O(n log^2 n) space for constant values of eps . It relies on a variation of the local-ratio theorem, which may be of independent interest in the semi-streaming model.
