  For several years, students visit us on different occasions at the
university. But how to bridge from the school curriculum to the contents of the
university mathematics? And how to find a focal point at which an active
contribute, despite the lack of knowledge, in view of limited time is possible?
Our approach: Translate,under guidance, everyday life optimization problems
into the language of mathematics, i.e. using variables, target functions,
equations and inequalities. These so-called integer linear programming models
are then solved by standard software. In this report we wnat to tell about the
lessons we have learned.
