Computing and Mathematical Sciences Colloquium

Faster Convex Optimization: Simulated Annealing with an Efficient Universal Barrier
Professor Elad Hazan, Department of Computer Science, Princeton University

Interior point methods and random walk approaches have been long considered disparate approaches for convex optimization. We show how simulated annealing, one of the most common random walk algorithms, is equivalent, in a certain sense, to the central path interior point algorithm applied to the entropic universal barrier function. Using this observation we improve the state of the art in polynomial time convex optimization in the membership-oracle model.
