  1. Resource Description
    "COLUMBUS is a collection of programs for high-level ab initio molecular electronic structure calculations. The programs are designed primarily for extended multi-reference (MR) calculations on electronic ground and excited states of atoms and molecules. A variety of methods, including - MCSCF (multiconfiguration self-consistent field) - MR-CISD (multireference configuration interaction with all single and double excitations), - MR-ACPF (multireference averaged coupled-pair-functional) and - MR-AQCC (multi-reference average quadratic coupled-cluster) are available. An important feature of COLUMBUS is its flexibility. In addition to standard classes of reference wave functions, such as CAS or RAS, calculations can be performed with selected reference configurations. Though the multi-reference aspect of COLUMBUS is emphasized, single-reference calculations can also be carried out very efficiently."
