Identification of Active Subfunctions in Finite-Max Minimisation via a Smooth Reformulation
Charl Ras, Matthew Tam, Daniel Uteda
In this work, we consider a nonsmooth minimisation problem in which the objective function can be represented as the maximum of finitely many smooth ``subfunctions''. First, we stu…

Bregman Golden Ratio Algorithms for Variational Inequalities
Matthew K. Tam, Daniel J. Uteda
Variational inequalities provide a framework through which many optimisation problems can be solved, in particular, saddle-point problems. In this paper, we study modifications to…
