摘要:

最近的电子图应用程序通常考虑具体的语义表达式,其中的概念等价源于具体的解释表达式。然而,适用于一种解释的等同性可能不适用于另一种解释。这种观察是可以利用的。我们认为抽象解释的应用程序的e-图,并表明,在一个e-图,格满足操作与抽象域有一个自然的解释为e-类,从而提高精度过近似。在这个扩展的摘要中,我们使用区间算术(IA)来说明这一点。

英文摘要:

Recent e-graph applications have typically considered concrete semantics of expressions, where the notion of equivalence stems from concrete interpretation of expressions. However, equivalences that hold over one interpretation may not hold in an alternative interpretation. Such an observation can be exploited. We consider the application of abstract interpretation to e-graphs, and show that within an e-graph, the lattice meet operation associated with the abstract domain has a natural interpretation for an e-class, leading to improved precision in over-approximation. In this extended abstract, we use Interval Arithmetic (IA) to illustrate this point.
