At each point in their domain, the value of such an operator can be expressed as a finite union of single-valued averaged nonexpansive operators. We investigate various structural properties of the class and show, in particular, that is closed under taking unions, convex combinations, and compositions, and that their fixed point iterations are locally convergent around strong fixed points. We then systematically apply our results to analyze proximal algorithms in situations, where union averaged nonexpansive operators naturally arise. In particular, we consider the problem of minimizing the sum two functions, where the first is convex and the second can be expressed as the minimum of finitely many convex functions.]]> Tue 24 Jan 2023 15:55:11 AEDT ]]> Variational analysis down under open problem session https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:47609 Tue 24 Jan 2023 11:14:45 AEDT ]]> Constraint Reduction Reformulations for Projection Algorithms with Applications to Wavelet Construction https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:40664 Thu 28 Jul 2022 11:42:05 AEST ]]> A Lyapunov Function Construction for a Non-convex Douglas-Rachford Iteration https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:42729 Thu 22 Jun 2023 11:58:43 AEST ]]> Generalized linear complementarity problems treated without fixed-point theory https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:14050 Sat 24 Mar 2018 08:22:37 AEDT ]]> A cyclic Douglas-Rachford iteration scheme https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:18073 Sat 24 Mar 2018 08:06:13 AEDT ]]> A trust region method for the solution of the surrogate dual in integer programming https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:27962 Sat 24 Mar 2018 07:38:46 AEDT ]]> A variational approach to Lagrange multipliers https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:27999 Sat 24 Mar 2018 07:38:40 AEDT ]]> Maximal monotone inclusions and Fitzpatrick functions https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:27998 gap functions. We propose a very natural gap function for an arbitrary maximal monotone inclusion and will demonstrate how naturally this gap function arises from the Fitzpatrick function, which is a convex function, used to represent maximal monotone operators. This allows us to use the powerful strong Fitzpatrick inequality to analyse solutions of the inclusion. We also study the special cases of a variational inequality and of a generalized variational inequality problem. The associated notion of a scalar gap is also considered in some detail. Corresponding local and global error bounds are also developed for the maximal monotone inclusion.]]> Sat 24 Mar 2018 07:38:40 AEDT ]]> Recent results on Douglas-Rachford methods for combinatorial optimization problems https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:28771 Sat 24 Mar 2018 07:23:45 AEDT ]]>
