multiconfiguration SCF method

https://doi.org/10.1351/goldbook.MT07075
Configuration-interaction method in which simultaneous optimization of both the shapes of molecular orbitals and contributions from different electronic configurations is carried out by using the variational method.
Note:
The MCSCF method with a large enough set of configurations allows a better estimation of the non-dynamic @C01349@ than the conventional CIS, CID, and CISD methods.
