Leveraging Christoffel-Darboux Kernels to Strengthen Moment-SOS Relaxations
Srećko Ðurašinović, Perla Azzi, Jean-Bernard Lasserre +3
The classical Moment-SOS hierarchy allows one to approximate the global minimum of a polynomial optimization problem through semidefinite relaxations of increasing accuracy. For ma…

The distance to cubic symmetry class as a polynomial optimization problem
Perla Azzi, Rodrigue Desmorat, Boris Kolev +1
Generically, a fully measured elasticity tensor has no material symmetry. For single crystals with a cubic lattice, or for the aeronautics turbine blades superalloys such as Nickel…
