The aim of the workshop is to bring together senior and especially junior researchers who work on optimization problems in discrete geometry (like for instance sphere packing or energy minimization). The focus will be on computational and experimental mathematical techniques. With short talks and many discussions we want share our computational tools, find their current limitations, and identify exciting problems which might help to shape the field in the near future.<\/p>\n\n\n\n
