Safeguarded Anderson acceleration for parametric nonexpansive operators
This paper describes the design of a safeguarding scheme for Anderson acceleration to improve its practical performance and stability when used for first-order optimisation methods. We show how the combination of a nonexpansiveness condition, conditioning constraints, and memory restarts integrate w...
