SCIP Optimization Suite 10.0: Exact Solving, Better Decompositions, and a More Productive Ecosystem
TL;DR: SCIP Optimization Suite 10.0 brings a numerically exact solving mode for rational MILPs, noticeable performance gains for MILP/MINLP, stronger presolving and symmetry handling, better heuristics and conflict analysis, IIS detection, and major updates to GCG, PaPILO, PySCIPOpt, and MIP-DD.

Happy to share our preprint on AAA rational approximation for photonic fibers doi.org/10.48550/arX...! We show how to compute only the fundamental modes within a dense spectrum of nonrelevant modes. Many thanks to my colleagues @cnoatzib.bsky.social, @zuseinstitute.bsky.social, @jcmwave.bsky.social!
