SCIP Optimization Suite 10.0 is out 🎉 → Numerically exact solving mode for rational MILPs → 9-20% faster on hard MINLPs → IIS detection for debugging infeasible models → Better symmetry handling ... and many more For full details see: www.pokutta.com/blog/resear... #optimization

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.

Uncovering Hidden Resonances in Non‐Hermitian Systems with Scattering Thresholds

The points where diffraction orders emerge or vanish in the propagating spectrum of periodic non-Hermitian systems are referred to as scattering thresholds. Close to these branch points, resonances f...

A Framework to Compute Resonances Arising from Multiple Scattering

Photonic resonances frequently arise from the interaction among multiple scatterers. It is shown how prior knowledge of such constituents can be used to compute resonances in nanophotonic systems eff....
