EvoSim is a self‑evolving AI scientist that autonomously refines physics‑based models by using experimental discrepancies to revise mechanisms and equations, and by testing plausibility against held‑out data. It records exploration traces to update its knowledge, skills, and multi‑agent coordination, thereby improving both the models and its own modeling decisions. In two industrial battery tasks, EvoSim achieved a 1.79 % mean absolute error in predicting lithium‑metal‑plating onset and a 7.62 mV root‑mean‑square error in dynamic voltage prediction, outperforming human‑developed models and reducing physics errors by about 36 %.

The article discusses how the rapid development of artificial intelligence (AI) and machine learning (ML) is transforming chemical engineering by influencing problem formulation, analysis, and solution across a wide range of applications, from atomic-scale simulations to industrial operations. It highlights recent methodological advances and representative uses, noting a shift from purely black-box models to hybrid and physics-informed frameworks that incorporate conservation laws, thermodynamic consistency, and structural constraints. These integrated approaches enhance robustness, reliability, and human-AI collaboration, ultimately amplifying rather than replacing core chemical engineering principles.

AutoREC is an open‑source Python platform that uses reinforcement learning to automatically generate equivalent circuit models (ECMs) from electrochemical impedance spectroscopy (EIS) data. The platform frames ECM generation as a Markov decision process, training a Double Deep Q‑Network agent that iteratively modifies circuit topologies based on state, actions, and model feedback. It supports end‑to‑end workflows—including EIS preprocessing, agent training, ECM generation, and visualization—and has been demonstrated on synthetic datasets and real experimental spectra from batteries, corrosion, oxygen evolution, and CO₂ reduction systems.
