The Bedwyr system for model checking over syntactic expressions
<|reference_start|>The Bedwyr system for model checking over syntactic expressions: Bedwyr is a generalization of logic programming that allows model checking directly on syntactic expressions possibly containing bindings. This system, written in OCaml, is a direct implementation of two recent advances in the theory of proof search. The first is centered on the fact that both finite success and finite failure can be captured in the sequent calculus by incorporating inference rules for definitions that allow fixed points to be explored. As a result, proof search in such a sequent calculus can capture simple model checking problems as well as may and must behavior in operational semantics. The second is that higher-order abstract syntax is directly supported using term-level $\lambda$-binders and the $\nabla$ quantifier. These features allow reasoning directly on expressions containing bound variables.<|reference_end|>
