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)”

## Visitors for Generalized Algebraic Data Types in OCaml (completed)

Algebraic datatypes (ADTs) [1] are the basic method for defining how to build complex data values in functional programming languages: they specify both the basic, or atomic, values, as well as the constructors for building larger values out of smaller ones. For example, the following ADT defines generic lists that contain values of type ‘a … full description “Visitors for Generalized Algebraic Data Types in OCaml (completed)”
