摘要: In this paper, we show that it is possible to abstract program fragments using real variables formulas in the theory of closed fields. This abstraction compositional and modular. We first propose an exact for programs without loops. Given domain (in a wide class including intervals octagons), then how obtain optimal with respect domain. allows computing fixed points inside domain, need widening operator.
