Optimisation Days 2026

About the workshop

Optimisation Days is a workshop that brings together researchers from across the broad field of optimisation, continuing from the successful meeting held in November 2025. The workshop offers a platform for presenting and discussing both established and emerging developments, with a particular emphasis on theory and fundamental questions in optimisation, alongside 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.

If you are interested in participating, please contact the organisers.
