New algorithm tackles evolving convex optimization problems

Researchers have developed a new online algorithm for convex optimization problems with evolving feasible sets and time-varying loss functions. This algorithm, an extension of the previously introduced CONES framework, aims to minimize both regret against a static optimal benchmark and the total movement cost. The projected proximal algorithm achieves a simultaneous regret and movement cost of O(T^{1-eta}) and O(T^eta) respectively for any {eta} in [0,1) over a time horizon T when loss functions are convex. For strongly convex loss functions, the algorithm achieves O(1) regret and O(log T) movement cost. AI
