“…One of the main advantages of such constraint-based approaches is that they are goal-oriented. But, on the other hand, they still require the computation of several Gröbner Bases [13] or require first-order quantifier elimination [14,15], and known algorithms for those problems are, at least, of double exponential complexity. Alternatively, SAT Modulo Theory decision procedures and polynomial systems [16,17,9,18,19] could also, eventually, lead to decision procedures for invariant generation.…”
