In this study, we apply FB-ENM to the direct MaxFlux method to determine the optimal path. With the FB-ENM defined here, it is possible in many cases to connect the reactant and product by a path with a constant FB-ENM energy of zero, meaning any point along the path is the highest energy point. Consequently, the problem regarding the low-energy region does not arise, making FB-ENM and the MaxFlux method well-suited for each other.
