Given deterministic interfaces P and Q, we investigate the problem of synthesising an interface R such that P composed with R refines Q. We show that a solution exists iff P and Q ...

Testing a deterministic implementation against a non-controllable non-deterministic stream X-machine
14 years 15 days ago
A stream X-machine is a type of extended finite state machine with an associated development approach that consists of building a system from a set of trusted components. One of th...
