Level 0/1

Alwen Tiu and Gopalan Nadathur were members of the Parsifal team during various parts of 2004. During their visits, the team developed a new architecture for automatically computing with expressions involving bound variables within fixed points of finite processes. The system was implemented in Standard ML and is called Level 0/1 . This system has been used to do model checking style deduction, search for winning strategies in game playing, and bisimulation checking for the $ \pi$ -calculus. The system is described in [14] and is available from the Web.

Recently David Baelde and Axelle Ziegler have reimplemented this system in Ocaml. Extensions and improvements with this system are planned for the Ocaml version.
