Notes:
Energy optimization (Eo) and property optimization (PO) were performed on the H2O molecule. A definition of the “optimality” κ, a dimensionless quantity of the form \documentclass{article}\pagestyle{empty}\begin{document}$$ {\rm optimality} \equiv \kappa = \left({\sum\limits_i {\left[{\omega _i \left\langle {\hat o} \right\rangle _i - O_i } \right]^2 } } \right) $$\end{document}has been proposed where ωi is a weighting factor, 〈ǒ〉i is the computed observable, and Oi is the corresponding property measured experimentally. The minimization of κ leads to property optimization methods (POM) which is a useful alternative to energy optimization methods (EOM).
