OPTXC

A machine learning toolkit for optimizing exchange-correlation functionals in linear-response TDDFT calculations. Supports multiple functionals (LC-wPBE, wB97XD) and optimization models (XGBoost, Random Forest, Gradient Boosting, CatBoost). Transforms SMILES strings into molecular descriptors for functional optimization.
