Truncated Configuration Interaction

Truncated Configuration Interaction is a computational quantum chemistry method that restricts the full configuration interaction expansion by including only a subset of electron correlation effects through a selected truncation of excitation levels, thereby distinguishing it from the exhaustive diagonalization of the Hamiltonian in full configuration interaction.
