LLMs enhanced with reinforcement learning for controllable molecular optimization

Researchers have introduced C-MORAL, a new reinforcement learning framework designed to enhance the capabilities of large language models in molecular optimization. This framework addresses the challenge of aligning LLMs with complex and competing drug design constraints by employing group-based relative optimization and continuous reward aggregation. Experiments on the C-MuMOInstruct benchmark demonstrated that C-MORAL significantly outperforms existing models, achieving a Success Optimized Rate of 48.9% on in-domain tasks and 39.5% on out-of-domain tasks while maintaining scaffold similarity.
