Images

Here are some images that I computed during my projects:

Poster from a BMBF workshop 2013, that won the price for best poster design.
Topology optimization problem via a mixed integer SOCP model
Testcase of placment of hangers under stressconstraints
Optimized system of pipes (from Bilfinger) with hangers
Run of a derivative-free optimization algorithm that tries to minimize a function only with the use of function evaluations
