◆ analytic_gradient_implemented()

bool sc::TaylorMolecularEnergy::analytic_gradient_implemented ( ) const

protectedvirtual

must overload this in a derived class if analytic gradient can be computed

Returns: true (analytic gradient is available) or false (analytic gradient is not available, default)

Reimplemented from sc::MolecularEnergy.

◆ analytic_hessian_implemented()

bool sc::TaylorMolecularEnergy::analytic_hessian_implemented ( ) const

protectedvirtual

must overload this in a derived class if analytic hessian can be computed

Returns: true (analytic hessian is available) or false (analytic hessian is not available, default)

Reimplemented from sc::MolecularEnergy.

◆ compute()

void sc::TaylorMolecularEnergy::compute ( )

virtual

Recompute at least the results that have compute true and are not already computed.

This should only be called by Result's members.

◆ save_data_state()

void sc::TaylorMolecularEnergy::save_data_state ( StateOut & )

virtual

Save the base classes (with save_data_state) and the members in the same order that the StateIn CTOR initializes them.

Reimplemented from sc::MolecularEnergy.

◆ value_implemented()

int sc::TaylorMolecularEnergy::value_implemented ( ) const

virtual

Returns: 1 (value implemented) or 0 (value not implemented, default). Must be overridden for the class to be useful.

Reimplemented from sc::Function.
