About the workshop

Optimisation Days is a workshop that brings together researchers from across the broad field of optimisation. It offers a platform for presenting and discussing both established and emerging trends, spanning theoretical, computational, and applied perspectives. By fostering exchange across these diverse areas, the workshop aims to promote cross-disciplinary dialogue, showcase recent advances, and stimulate new collaborations in the study and practice of optimisation.

The event features a NEXUS Lecture by James Saunderson on the afternoon of 12 November followed by a reception.
