Z3's quantifiers have been replaced by functions which generate finite conjunctions and disjunctions, leading to a massive performance gain. The following new features have also been included:

  • The user can specify a max_time and is prompted to increase the time if the model-checker times out.
  • The user can set an optimize variable with override flag -o to have the model-checker find a model with the smallest number of atomic elements within the max_time.
  • The user can set the contingent variable with override flag -c to require all propositions to be contingent, i.e., to have some possible verifier and some possible falsifier. Since the null state cannot verify nor falsify a contingent proposition, constraints on propositions to only have non-null verifiers and falsifiers have been removed.

In addition to these features, the unit tests have been expanded to now include 120 examples which are divided by logical operators.
