Optimal discrete pipe sizing for tree-shaped CO2 networks
Jaap Pedersen, Thi Thai Le, Thorsten Koch +1
Many energy-intensive industries, like the steel industry, plan to switch to renewable energy sources. Other industries, such as the cement industry, have to rely on carbon capture…
Progress in Mathematical Programming Solvers from 2001 to 2020
Thorsten Koch, Timo Berthold, Jaap Pedersen +1
This study investigates the progress made in LP and MILP solver performance during the last two decades by comparing the solver software from the beginning of the millennium with t…
Controlling transient gas flow in real-world pipeline intersection areas
Felix Hennings, Lovis Anderson, Kai Hoppmann-Baum +2
Compressor stations are the heart of every high-pressure gas transport network. Located at intersection areas of the network they are contained in huge complex plants, where they a…
Generative deep learning for decision making in gas networks
Lovis Anderson, Mark Turner, Thorsten Koch
A decision support system relies on frequent re-solving of similar problem instances. While the general structure remains the same in corresponding applications, the input paramete…
First Experiments with Structure-Aware Presolving for a Parallel Interior-Point Method
Ambros Gleixner, Nils-Christian Kempke, Thorsten Koch +2
In linear optimization, matrix structure can often be exploited algorithmically. However, beneficial presolving reductions sometimes destroy the special structure of a given proble…
Reduction-based exact solution of prize-collecting Steiner tree problems
Daniel Rehfeldt, Thorsten Koch
The prize-collecting Steiner tree problem PCSTP is a well-known generalization of the classical Steiner tree problem in graphs, with a large number of practical applications. It at…
