These cases show that a fixed policy, even when tuned by hand, can demonstrate particularly poor performance for some compositions, for example, in the original FUSE study the global minimum for SrY2O4 was not obtained. In this work, the Uniform policy for Y2O3 and the Original policy for SrY2O4 both have a low success rate at finding their respective energy minima. The dynamic RL-CSP policy reliably improves the Uniform starting policy for both materials, taking at most 56-71% of steps required by the initial fixed policy.
