Fasteners number optimization

Hello! My name is Tatiana Pogarskaia and I am one of the PhD students working for the VIM Lab. Today I would like to tell some words about my current research. The research was mostly caused by one of the projects under our collaboration with Airbus SAS Company and it is certainly connected with the […]

Shape optimization to minimize failure probability (and material consumption)

Movie: Shape flow for a 2D rod towards optimal reliability.   As three working groups (Optimization, High Performance Computing and Stochastics) at the IMACM in Wuppertal, we develop probabilistic shape optimization models for different failure mechanisms, notably for low cycle fatigue (LCF) problems, with gradient based methods. Low cycle fatigue is a surface driven failure […]

Optimal maintenance of wind power plants

My name is Quanjiang Yu, and I am a PhD student in the optimization group at the Department of Mathematical Sciences, Chalmers University of Technology and University of Gothenburg. My research project ‘’Optimal maintenance of wind power plants’’ is financed by the Swedish Wind Power Technology Centre (SWPTC) and the Swedish Research Council. My supervisor […]

Intersection-free load balancing for industrial robots

My name is Edvin Åblad, and I am an industrial PhD student at the Fraunhofer Chalmers Research Centre  (FCC) in the department of geometry and motion planning. I am also part of the optimization group at the Department of Mathematical Sciences, Chalmers University of Technology and University of Gothenburg.  My research project is part of […]

Topology Optimization and Risk Management

Efficient design is one of the most important objectives in modern engineering. In a multitude of applications this requires the balancing of cost savings and risk management. In the design of load bearing structures it is the goal to minimize material usage and weight while still ensuring design limits and constraints. Less material in key […]

Performance Measures for Algorithmic Trading

Automated Order Execution is the dominant way of executing trade orders for the last couple of years at major stock markets. There is a variety of algorithms that are designed to serve different purposes and traders preferences. In Automated Order Execution a computer-based algorithm is used to buy (or sell) a position while attempting to […]

VF2++ – a subgraph isomophism algorithm for molecular pattern matching

In a previous blog entry, we introduced COIN-OR::LEMON (, the open source C++ graph and network modelling library. As we mentioned there, this library targets both academic and industrial applications. In this post a use-case for the latter is shown.   Last year, QuantumBio Inc.1 approached us with a simple request: they were using LEMON […]
