Unlike the heavy-molecule dataset, dUCT-v1 solved a lower number of molecules than UCT, and dUCT-v2 solved ~0.1% more molecules. This is likely due to the difference in complexity between the two datasets. dUCT was developed to search more at high depths of the tree, to target routes which are difficult to solve. The increased total solve percentage (UCT solved 76.4% of the 50K
