Classification: 2.1.

Nature of problem:
Generating the list of configuration states with taking into account multiple additional constraints of different types.

Solution method:
Building the configuration state list for the set of the given configurations with further selection of necessary configuration states by applying a set of restrictions on each configuration.

For atomic configurations containing any electron shells with λ <= 3 momenta of the electron shells with λ > 3 and N <= 2 is restricted by L max = 6. The number of the active shells can not exceed seven.

Unusual features:
Possibility to select configuration states.

Running time:
Seconds to minutes. Depends on the size of the problem: of the order of seconds for simple configurations to minutes for a large set of very complex admixed configurations with f-electron shells.
