| assume_t0_q0x | - since it is extremely difficult to converge the iterative procedure using T as an optimized variable, assume T = T_0 + (1-R_0)*X and optimize X T_0 is assumed to be the zero-delocalization reference |
| perturbation_only | - perturbative (do not update Hamiltonian) |
| special_case | to reduce the overhead special cases are implemented: xalmo_case_normal - no special case (i.e. xALMOs) xalmo_case_block_diag xalmo_case_fully_deloc |
