Optimization for engineers

Short description

The basics of optimization are presented, with a focus on common and proven optimization methods for problems in the field of applied structural optimization.

An introduction provides basic knowledge of mathematical concepts and aspects of optimization. Afterwards, optimization problems without restrictions and problems with restrictions are considered. Based on this, alternative formulations of an optimization problem (so-called Lagrange duality) are presented with the help of Lagrange functions. Subsequently, approximation procedures, optimality criteria procedures and multi-criteria optimization are considered. Finally, perspectives on further areas such as shape optimization and topology optimization are given.
