The Multi-Reference Configuration Interation (MRCI) method accounts for dynamic correlation effects on top of a multiconfigurational wave function chosen as reference, generally of CAS type. Since the uncontracted MRCI approach can be expressed via RAS specifications, an efficient GAS algorithm could promptly allow uncontracted MRCI calculations. This is generally prohibitively expensive, considering the unfavorable exponential scaling of RAS wave functions with respect to the size of RAS1 and RAS3 spaces. However, it is feasible using our Stochastic-GAS algorithm, and an example is offered in Section 4.2.
