Researchers have developed new AI frameworks for molecular optimization, aiming to improve molecule properties while maintaining structural similarity. One approach, FORGE, uses a two-stage process that ranks and generates fragment replacements, outperforming larger models by leveraging explicit fragment-level supervision. Another method, SMER-Opt, employs a response-oriented discrete edit strategy with a single-step predictor and a multi-step planner to guide optimization trajectories through guided tree search. AI
