A variational expansion of an atomic state in multiple configuration-state functions, recovering correlation within the chosen basis and excitation space.

This is an authored directed relation from the source endpoint to the target endpoint.
Configuration interaction expands a state in determinants or configuration state functions within a finite one-particle basis.
The target is a member or subtype of the broader source class.

Configuration interaction expands a state in determinants or configuration-state functions; truncation controls cost but usually sacrifices size extensivity.
The target is a model, idealization, restricted ansatz, approximation scheme, phenomenological fit, or historical representation used for the source system or theory. It need not have a universal small error parameter and is not thereby a controlled limit or effective theory. The edge label and detail must identify the precise status.

Configuration interaction expands beyond one Hartree–Fock determinant using selected excited determinants or configuration-state functions in a finite basis.
A more specific theory, model, entity class, or regime is obtained by restricting or extending the scope of a broader framework.
