New Theory and New Practical Methods for Solving Large-Scale Linear and Conic Optimization
… interior-point methods) being replaced by the primal-dual hybrid gradient method (PDHG) to solve large-scale LP problems. While PDHG---with heuristic enhancements and GPU implementation---has been very successful in solving large-scale LP problems, its performance can have substantial variance …

Towards GPU-accelerated discrete optimization
… First, for bound computations, we develop HyLAC (Hybrid Linear Assignment solver in CUDA), the fastest known GPU-based solver for the Linear Assignment Problem (LAP). LAP is a fundamental combinatorial optimization problem with applications in tracking, scheduling, and resource allocation. HyLAC …

Anisotropic variational models and PDEs for inverse imaging problems
In this thesis we study new anisotropic variational regularisers and partial differential equations (PDEs) for solving inverse imaging problems that arise in a variety of real-world applications. Firstly, we introduce a new anisotropic higher-order total directional variation regulariser. We …
