This package contains the implementation for generating input files, particularly, MDP model, LTL/DRA model for the PRISM model checker, from NetworkX graph objects.
Creating by hand these modules is simply tedious, particularly so since PRISM does not allow non-integer identifier for each mode of a state.
- Generate product MDP model in PRISM language from MDP that are created as NetworkX graph objects.
Specifically, check the P_MDP_TG package to generate the product automaton from a (probabilistically-labeled) MDP and a LTL formula.
Then this PRISM module (example size5_all_base_nx2prism.nm) along with a trivia LTL formula (example size5_all_base_nx2prism.nm.props) can be fed directly to PRISM.
- Generate DRA model as MDP module in PRISM language.
Given a LTL formula, P_MDP_TG package provides automated translation to a NetworkX graph, via LTL2BA and LTL2DSTAR. Then the equivalent PRISM module as a MDP can be generated here.
Note that the DRA (example dra_all_base_nx2prism.nm) is encoded as a PRISM module to allow action-based LTL model checking (i.e., synchronized game between a MDP and a DRA), since PRISM only supports state-based LTL currently.
- Generate labeled MDP module in PRISM language, from NetworkX graph object.
Given a labeled MDP digraph, P_MDP_TG package generates the corresponding mdp module in PRISM language, see example size5_motion_mdp_nx2prism.nm
