We carry out state-of-the-art optimization of a nuclear energy density of Skyrme type in the framework of the Hartree-Fock-Bogoliubov (HFB) theory. The particle-hole and particle-particle channels are optimized simultaneously, and the experimental data set includes both spherical and deformed nuclei. The new model-based, derivative-free optimization algorithm used in this work ��

Error Estimates of Theoretical Models: a Guide (2014, methodology): “Optimization of nuclear energy density functionals (EDFs) using different data categories were carried out for nuclei [17, 26, 27, 21] and for nuclei and neutron stars [28].”
Symmetry Parameter Constraints from a Lower Bound on Neutron-matter Energy (2016, methodology): “…of the parameter sets taken from the compilations of Dutra et al. (2012, 2014) do not satisfy the UG constraint, a larger fraction of the accepted parameter sets do obey this constraint; furthermore, they show almost exactly the same correlation as in the analysis of Kortelainen et al. (2010).”
Density functional theory: Its origins, rise to prominence, and future (2015, methodology): “The dynamical mean-field theory (DMFT) (Georges et al., 1996; Kotliar and Vollhardt, 2004) is a mapping of lattice models onto quantum impurity models subject to a selfconsistency condition, and the “LDAþ DMFT” method merges the DF theory with a modern many-body approach.”
Future of nuclear fission theory (2020, result): “They allow a sensitivity analysis to check the impact of a certain model parameter on an observable (Kortelainen et al 2010, Kortelainen et al 2012) and they indicate the information content of a new observable as compared to previous ones (Reinhard and Nazarewicz 2010, McDonnell et al 2015).”
Nuclear equation of state from ground and collective excited state properties of nuclei (2018, methodology): “In a different work [140], a Skyrme EDF was presented together with an exhaustive evaluation of statistical theoretical errors.”
