Hoare Logic 推出后在程序正确性证明方面成为了利器,然而它有一点没有包含,就是没有处理指针,于是 John C. Reynolds 等扩展的 Separation Logic 很好地处理了指针相关的内容。 Separation Logic 中的程序状态分为两个部分:栈区s和堆区h,堆h定义为地址到值的函数。两个堆正交若且唯若其定义域不交,记作h1⊥h2。

霍尔逻辑(Hoare Logic)是一种形式系统,在软件工程中用于计算机系统正确性的验证,霍尔三元组是霍尔逻辑中最基础的公式表示。 霍尔三元组的组成:P是“前置条件”,S为“操作”,Q为P经过S后达到的后置条件 霍尔三元组 例子1 举一个霍尔逻辑的一个简单应用例子1: {x≠0} //{P}前置条件,用{}框起来 y=x*x; ...

Hoare logic is the fundamental formalism introduced by C.A.R. Hoare in 1969 for reasoning about the correctness of imperative programs, building on first-order logic. In this chapter we study a program logic which is a variant of Hoare logic for programs containing user-provided annotations.The...
General Way and Example to Verify the Correctness of Program Using Hoare Logic YANG Jing Abstract: This paper shows how to verify the correctness of program with respect to a language in the frame of Hoare logic, and gives a detailed example to validate this method. The future research ...

| 关于完全正确的while规则,WP似乎告诉我,仅找到严格减少的循环变量就足以证明终止。我不能接受,因为我遗漏了一些东西或规则是错误的。考虑 int i = 1000; while(true) i--; 其中变量 i 的值是严格递减的循环变量,但循环肯定不会终止。 当然,该规则需要具有其他先决条件,例如i <0→¬B(其中B是公理模式中...
I found it particularly funny that we should be the ones to give a Hoare logic to CSP, while Hoare was using essentially behavioral methods to reason about CSP programs. I’m still waiting for the laughter. (在新选项卡中打开) Copyright © 1984 by the Association for Computing Machinery,...
