摘要

我们描述了一个简单而有效的算法来证明一类具有非线性变量赋值的循环的终止。该方法基于对回路终止条件影响锥上的每个变量的散度检验。分析允许我们自动证明使用以前的技术无法处理的循环的终止。本文最后给出了从工业规范中抽取的简短示例的实验结果。

Proving Termination by Divergence

We describe a simple and efficient algorithm for proving the termination of a class of loops with nonlinear assignments to variables. The method is based on divergence testing for each variable in the cone-of-influence of the loop's termination condition. The analysis allows us to automatically prove the termination of loops that cannot be handled using previous techniques. The paper closes with experimental results using short examples drawn from industrial code.
