A computational materials study 공개 that automates transition-state search with an agentic LLM

How to apply this

You can directly try a computational experiment that repeatedly improves the search procedure by targeting failure cases in transition-state search code.

1. Gather only the reactions that have not yet yielded a transition state and organize the reactants, products, and initial estimated paths.
2. Have an LLM-based agent modify the search code, and repeatedly run transition-state optimization and path-tracing calculations for each modified version.
3. Inspect the candidate structures from each attempt with eigenvector analysis and record pass or fail by confirming connectivity between the two endpoints of the reaction path.
4. Compare which procedure worked for each failure case and prioritize the search branch that is more suitable in the next iteration.

Data needed

You need the structures of reactants and products for reactions that have not yet yielded a transition state, initial transition-state guesses, computational conditions, and the energy and geometry optimization results from each attempt.

Checking the result

Use eigenvector analysis to confirm whether the transition-state candidate is a true saddle point, and independently revalidate whether both endpoints of the reaction path connect to the reactant and product, respectively.

What can go wrong

The most common failure is to exaggerate improved success rates in computational datasets as real reaction or process performance gains, and the search code may be tuned only to specific failure patterns in the dataset and may not generalize to other reaction systems.
