Title: Structure, Analysis, and Synthesis of First-Order Algorithms
Abstract:
Optimization algorithms can be interpreted through the lens of dynamical systems as the interconnection of a linear system and a set of subgradient nonlinearities. This dynamical systems formulation allows for the analysis and synthesis of optimization algorithms by solving robust control problems. In this work, we use the celebrated internal model principle in control theory to structurally factorize convergent optimization algorithms into a suitable network-dependent internal model and a core subcontroller. As the key benefit, we reveal that this permits us to synthesize optimization algorithms even if information is transmitted over networks featuring phenomena such as time delays or channel memory. Design of these certified-exponentially-convergent networked algorithms is achieved under bisection in the convergence rate through either a nonconvex local search or by alternation of convex semidefinite programs. We demonstrate factorization of existing optimization algorithms and the automated synthesis of new optimization algorithms in the networked setting.

Jared Miller is currently a Postdoctoral Researcher at the Chair of Mathematical Systems Theory at the University of Stuttgart working with Prof. Carsten Scherer. He received his B.S. and M.S. degrees in Electrical Engineering from Northeastern University in 2018, and his Ph.D. degree from Northeastern University in 2023 under the advisorship of Mario Sznaier (Robust Systems Laboratory). He was previously a Postdoctoral Researcher Automatic Control Laboratory (IfA) at ETH Zurich, in the research group of Prof. Roy S. Smith. He was given an Outstanding Student Paper award at the IEEE Conference on Decision and Control in 2021 and in 2022, and was a finalist for the Young Author Award at the 2023 IFAC world congress. His research interests include
renewable energy integration, convex optimization, safety analysis, and control of nonlinear systems.
