Most chemical reactions require molecules to overcome energy barriers. Locating the transition state (TS), the highest energy point along the barrier, is crucial for a deeper understanding of the reaction. Computational methods for finding TSs or reaction paths can be classified into single-ended and double-ended approaches. Single-ended methods search for the TS by updating a single molecular structure, while double-ended methods optimize the reaction path connecting known reactant and product. This study focuses exclusively on the latter.
