Summary

• What is new: A novel approach to RNA design by formulating the problem as continuous optimization and using an expected partition function for optimization.
• Why this is important: RNA design tasks are challenging due to their nature as discrete optimization problems, and some are even NP-hard, making them particularly difficult to solve with conventional local search methods.
• What the research proposes: The paper introduces a framework that transforms the discrete optimization problem into a continuous one, leveraging an expected partition function and gradient descent-based methods to iteratively refine solutions towards optimal RNA sequences.
• Results: The method consistently outperforms the existing LinearDesign approach in optimizing mRNA for ensemble free energy, especially on longer sequences, demonstrating its efficacy in complex RNA design tasks.
