The Population Controversy and Beyond,s illustrated how the Hellmann-Feynman theorem may be applied directly to SCF and limited CI wave functions once the right orbital connections have been chosen. Some computational aspects are considered and finally the relation to covariant derivatives in differential geometry is discussed.

Strategies of Gradient Evaluation for Dynamical Electron Correlation,round-state) molecules, with special emphasis on gradient evaluation. We shall also compare functional based methods with non-functional based ones for gradient calculation. The combined use of a high-level method without gradients and a low-level method with gradients is discussed.
