Better known for modelling discrete-continuous optimisation problems than optimising points of sail, and far more comfortable on land discussing how to simulate gas flows than determining how to navigate tidal waters, Prof. Dr. Günter Leugering led a team of five researchers representing The Chairs of Economics – Discrete Optimization – Mathematics (EDOM) and their international guests on leg 2 of Science Sets Sail this summer. We asked him why he decided to take part in Science Sets Sail.
