Overview

Save Big on Coursera Plus. 7,000+ courses at $160 off. Limited Time Only!
Explore edge-weighted online bipartite matching in this 28-minute IEEE conference talk. Delve into competitive ratio, free disposal, and related works in adversarial order. Examine main results, including deterministic greedy and two-choice greedy algorithms with independent random bits and perfect negative correlation. Learn about online correlated selection (OCS) and three main tools: online primal-dual method, complementary CDF viewpoint, and updating dual variables. Analyze the edge-weighted matching algorithm and factor-revealing linear program. Conclude by discussing open problems in this field of algorithmic research.
