The keyval constructor reads the following keywords:.
|
|
An optimizer can call change coordinates periodically to give the function an opportunity to change its coordinate system. A return value of 0 means the coordinates were not changed. Otherwise, a transform object to the new coordinate system is return. The function object applies the transform to any objects it contains. This will obsolete the function data. Reimplemented in MolecularEnergy. |
|
If passed a nonzero number, compute the value the next time compute() is called. Return a nonzero number if the value was previously to be computed. |
|
Save the base classes (with save_data_state) and the members in the same order that the StateIn CTOR initializes them. This must be implemented by the derived class if the class has data. Reimplemented from SavableState. Reimplemented in MolecularEnergy, MBPT2, CLHF, CLSCF, HSOSHF, HSOSSCF, SCF, UnrestrictedSCF, OneBodyWavefunction, and Wavefunction. |
