Where academic tradition
meets the exciting future

Turku Optimization Group (TOpGroup)

The mathematical and computational tools in optimization are used more frequently these days, as they provide efficient tools with negligible costs for many industries in the race for greater profits and better efficiency. The optimization group does research in both modeling and implementation of practical problems from industry and further development of algorithms. The following areas of optimization are at focus:
