This is such a cool project that really deserves your attention - if you are even slightly interested in Optimization Benchmarking especially in the energy sector. Very well made app that makes it a joy to browse and discover!
New tool for modelers&solver devs! The Open Energy Benchmark lets you compare 5 OSS & commercial LP/MILP solvers across more model framework, enhancing speed, scale, transparency of the energy transition.

Germany together with our European allies stands united alongside #Ukraine - and against the Russian aggression. Ukraine can build on unwavering support from Germany, Europe and beyond. Their defence of democracy & their quest for peace & security is ours.
