In this talk we present an asynchronous multistart algorithm for identifying high-quality local minima. We highlight strong theoretical results that limit the number of local optimization runs under reasonable assumptions. Though the results are valid whether or not the derivative of the objective function exists, the method's efficient use of previously evaluated points makes it well-suited for finding minima when the objective is expensive to evaluate.
