At high intra-atomic separations, the necessary parameters to achieve chemical accuracy in the (very) strongly correlated limit seem to limit toward a unified value of roughly 25% of the determinant space. We note that there is no orbital optimization in either the RLCI or HCI methods presented here, which may prove beneficial in cases such as these. Or, there may simply be limits to how well determinant-based methods can compress the wave function and other wave function ansätze, such as matrix or tensor product states may prove more efficient. Utilizing configuration state function (CSFs) may also additionally compress the wave function, though the RLCI will lose some of the computational advantages of a determinant-based approach. Thus, further improvements may be found in both extending RLCI to treat orbital optimization, as well as extending RL methods to optimize nondeterminant-based wave function ansätze, like CSFs or tensor product states.
