Therefore, weighting the search towards exploitation while shallow, would reduce exploration of worse nodes. Furthermore, when one gets deeper into the tree, there are fewer available disconnections at each node. We have established from eUCT that the probability of success is higher when deeper in the tree. It would, therefore, be more effective to explore more available disconnections when closer to a leaf-node, as there is a greater probability of locating successful routes. This method is only beneficial due to the pre-determined value network in AiZynthFinder.
