Learning-based branching strategies for mixed-integer programming

Arne Schulze (Chair of Business administration, HSU) A Mixed-integer programming (MIP) model solved by the Branch-a-Bound (B&B) method is the main exact solution strategy in combinatorial optimization like in production and logistics. The aforementioned optimization problems are typically NP-hard to solve such that a vast amount of computation power is…

Nozzle Design in Cold Spray Applications

Julio Gutierrez (Materials Technology, HSU) In cold spray, the critical velocity defines the minimum velocity that the particles must reach in order to adhere to the substrate. The more particles exceeding this critical velocity, the higher are the efficiency of the process and the deposit quality. Individually needed process conditions…
