(a) (b) Finally, we explore the symmetric dissociation of the H 8 chain in Fig. . Despite its apparent simplicity, this is a challenging system with rapidly increasing amounts of strong correlation as the system dissociates. This is reflected in the linear increase in log error in Fig. , and the linear increase in determinants required for HCI to maintain its subchemical accuracy observed in Fig. . Despite these challenges, RLCI is able to obtain better accuracy for fewer determinants compared to HCI for most points along the dissociation curve, similar to what has been observed in the other prototype calculations for CO and N 2 .
