FMplex: A Novel Method for Solving Linear Real Arithmetic Problems

In this paper we introduce a novel quantifier elimination method for conjunctions of linear real arithmetic constraints.

Zusammenfassung:	In this paper we introduce a novel quantifier elimination method for conjunctions of linear real arithmetic constraints. Our algorithm is based on the Fourier-Motzkin variable elimination procedure, but by case splitting we are able to reduce the worst-case complexity from doubly to singly exponential. The adaption of the procedure for SMT solving has strong correspondence to the simplex algorithm, therefore we name it FMplex. Besides the theoretical foundations, we provide an experimental evaluation in the context of SMT solving.
