BBI的标号序列演算:证明理论与证明搜索

A Labelled Sequent Calculus for BBI: Proof Theory and Proof Search

Zhe Hou, Alwen Tiu, Rajeev Gore

摘要:

我们提出了一个标记的布尔BI演算,一个经典的变种的O'Hearn和Pym的逻辑的集束蕴涵。微积分是简单的,健全的,完整的,并享受削减消除。我们表明,在我们的证明系统中的所有结构规则,包括那些规则,操纵标签,可以本地化周围的应用程序的某些逻辑规则,从而本地化这些规则的处理证明搜索。在此基础上,我们展示了一个自由变量演算,处理结构规则懒在约束系统。最后提出了一种求解约束的探试法,并给出了实验结果。

英文摘要:

We present a labelled sequent calculus for Boolean BI, a classical variant of O'Hearn and Pym's logic of Bunched Implication. The calculus is simple, sound, complete, and enjoys cut-elimination. We show that all the structural rules in our proof system, including those rules that manipulate labels, can be localised around applications of certain logical rules, thereby localising the handling of these rules in proof search. Based on this, we demonstrate a free variable calculus that deals with the structural rules lazily in a constraint system. A heuristic method to solve the constraints is proposed in the end, with some experimental results.
