DWIFOB: A Dynamically Weighted Inertial Forward-Backward Algorithm for Monotone Inclusions

Hamed Sadeghi, Sebastian Banert, Pontus Giselsson

We propose a novel dynamically weighted inertial forward-backward algorithm (DWIFOB) for solving structured monotone inclusion problems. The scheme exploits the globally convergent…

On compositions of special cases of Lipschitz continuous operators

Pontus Giselsson, Walaa M. Moursi

Many iterative optimization algorithms involve compositions of special cases of Lipschitz continuous operators, namely firmly nonexpansive, averaged and nonexpansive operators. The…

QPDAS: Dual Active Set Solver for Mixed Constraint Quadratic Programming

Mattias Fält, Pontus Giselsson

We present a method for solving the general mixed constrained convex quadratic programming problem using an active set method on the dual problem. The approach is similar to existi…

Nonlinear Forward-Backward Splitting with Projection Correction

Pontus Giselsson

We propose and analyze a versatile and general algorithm called nonlinear forward-backward splitting (NOFOB). The algorithm consists of two steps; first an evaluation of a nonlinea…

Operator Splitting Performance Estimation: Tight contraction factors and optimal parameter selection

Ernest K. Ryu, Adrien B. Taylor, Carolina Bergeling +1

We propose a methodology for studying the performance of common splitting methods through semidefinite programming. We prove tightness of the methodology and demonstrate its value…
