Capturing the PES is crucial for obtaining reasonable structure during geometry optimization because the PES represents the energy landscape of the system, mapping out how energy changes with variations in atomic positions. The inability of a trained MLIP to accurately capture the PES could result in missing low-energy configurations of the system or giving the structures that are physically not meaningful. Capturing correct PES across various regions is not an easy task. For instance, a recent study on the performance of MLIPs in capturing the PES of C dimer (C 2 ) revealed that despite correct representation around the equilibrium region, they encountered problems at C-C distances smaller/larger than equilibrium, resulting in overstabilized collapsed/dissociated structures. To evaluate how our ANN potential behaves across various regions of PES, we examined the potential energy curves associated with the C-C bond dissociation process in C 2 , ethyne (C 2 H 2 ), ethene (C 2 H 4 ), and ethane (C 2 H 6 ) and compared the results with DFT calculations.
