The algorithm uses two auxiliary procedures: a procedure for producing a candidate formula for quantifier elimination and a procedure for eliminating or partially eliminating quantifiers. We also apply the algorithm for Presburger Arithmetic formulas and evaluate it on formulas from a model checker for Duration Calculus [8]. We report on experiments on different variants of the auxiliary procedures. So far, there is an edge to applying SMT-TEST proposed in [10], while we found that a simpler approach which just eliminates quantified variables per round is almost as good. Both approaches offer drastic improvements to applying default quantifier elimination.
