However, d' ij refers to the minimum atom-to-atom distance when energy is minimized. We intend to use prior structural information to make adjustments via the interaction block, achieving a better fitting of d' ij . The ablation experiments prove that eliminating the interaction block leads to a performance decline on the FEP1 and FEP2 datasets, particularly on FEP1, where the Pearson correlation coefficient dropped from 0.646 to 0.547. This result also confirms that our pretrained model has indeed learned current-state distance distributions, evident in the tendency of the d' ij /d ij ratios for certain atoms to approach 1, a trend that gradually diminishes as the model iterates. The subsequent energy term calculations demonstrate that the van der Waals interaction and hydrophobic interactions constitute the largest proportion, primarily due to the integration of van der Waals force constraints into the loss function. While this method has its merits and limitations, it adequately satisfies the evaluation requirements for most interactions, albeit with potential deficiencies in specific cases.
