Hierarchy CI has been described in J. Phys. Chem. Lett. 2022, 13, 19, 4342–4349. It has been recently extended to seniority and hierarchy based CI in J. Chem. Theory Comput, doi:10.1021/acs.jctc.3c00946 (2023).
Since MACIS contains a high-throughput CI engine, these CI models might be interesting to have as well.
