To evaluate a property of the form 'for all x there exists some y' with a relational model finder requires a generator axiom to force all instances of y to exist in the universe of discourse. Without the generator axiom the model finder will produce a spurious counter-example by simply not including an important instance of y. Generator axioms are generally considered to be expensive to evaluate, significantly limiting the scope of the analysis. We demonstrate that evaluating the generator axiom in a separate stage from the property results in substantial improvements in analysis speed and scalability
