The frame problem was originally de ned in the context of the situation calculus. The problem also manifests itself in more sophisticated temporal logics that can represent interv...
There is a growing recognition of the need to apply formal mathematical methods in the design of \high con dence" computing systems. Such systems operate in safety critical co...
For specifying and verifying branching-time requirements, a reactive system is traditionally modeled as a labeled tree, where a path in the tree encodes a possible execution of the...
Policies are used to describe rules that are employed to modify (often distributed) system behaviour at runtime. Typically policies are created by many different people and there a...
