We present a proof-technique for reducing the nondeterminbstract agent specifications in a BDI framework by means of refinement. We implement the operational semantics of agent sp...
Higher-order recursion schemes are systems of rewrite rules on typed non-terminal symbols, which can be used to define infinite trees. The Global Modal Mu-Calculus Model Checking...
Expander2 is a flexible multi-purpose workbench for interactive rewriting, verification, constraint solving, flow graph analysis and other procedures that build up proofs or co...
