Two-stage Agent Program Verification

We describe an extension to the AJPF agent program model-checker so that it may be used to generate models for input into other, non-agent, model-checkers. We motivate this adaptation, arguing that it potentially improves the efficiency of the modelchecking process and provides access to richer property specification languages. We illustrate the approach by describing the export of AJPF program models to both the SPIN and Prism model-checkers. We also investigate, experimentally, the effect the process has on the overall efficiency of model-checking.
