Abstract interpretation provides a generic framework to design static analysis, and has been widely applied in analysis of real-world programs. The scalability and precision of these analyses depend largely on the chosen abstract domain. The template polyhedra domain is well-known for offering a compelling trade-off be...

A path-sensitive loop invariant inference approach based on Large Language Models and abstract interpretation that constructs candidate invariants as disjunctions of clause conjunctions satisfied by counterexamples across loop paths and iteratively refines them using counterexamples generated by the SMT solver during v...

Cloud computing infrastructure increasingly relies on cloud services where correctness is critical. Ensuring their correctness requires formal verification techniques grounded in rigorous mathematical reasoning. In practice, formal models of cloud services frequently exhibit multiple loop structures, and verifying such...

Multi-turn retrieval-augmented generation (RAG) improves question answering by decomposing evidence seeking into iterative retrieval and reasoning steps. Existing multi-turn RAG methods usually optimize when and how to retrieve while fixing the number of retrieved documents per step. However, we discovered that this fi...
