A Cyclic Prover for Propositional Dynamic Logic (available)

Propositional Dynamic Logic (PDL) [1] is a logic in which abstract properties about the behaviour of programs can be expressed, in a very general way. Because of its generality it is suitable for checking the behaviour or a wide range of programs and systems, via model checking. PDL is what is known as a modal … full description “A Cyclic Prover for Propositional Dynamic Logic (available)”

Cyclist: Verifying Programs using Cyclic Proof (available)

Cyclic proofs are a technique for proving properties inductively, or proving properties about inductively defined objects or processes. They can be used to prove logical statements, or to verify recursive programs. The Cyclist tool [1] has been developed as an automatic verification tool based on cyclic proofs. It can prove termination and verify temporal properties … full description “Cyclist: Verifying Programs using Cyclic Proof (available)”

Engineering ROTOR: a Refactoring Tool for OCaml (completed)

OCaml [1] is a mature functional programming language with an expressive type system. Recently, we have developed a prototype tool, called ROTOR, for automatically refactoring OCaml codebases [2]. Currently, ROTOR handles renaming of functions. This is surprisingly hard due to OCaml’s powerful module system: renaming a function in one module may actually require renaming functions … full description “Engineering ROTOR: a Refactoring Tool for OCaml (completed)”
