摘要 在并发程序的分析及验证过程中,不变式起着至关重要的作用,为了提高非线性不变式自动生成算法的效率及通用性,基于将非线性不变式生成问题转换为数值约束求解问题的思想,提出通过检验根理想的从属关系方法使算法具备处理通用代数变迁系统的能力;建立了基于吴方法的非线性不变式自动生成算法,该算法不使用加强的归纳条件,并可以直接处理约束方程. For the analysis and verification of concurrent program,invariant is a very important concept.In order to improve the efficiency and generality for non-linear invariant generation algorithm,this paper shows how to convert a non-linear invariant generation problem to a numerical constraint solving problem according to the radical membership of the corresponding ideal.A novel algorithm based on the Wu’s method is proposed,which does not use the stronger condition to solve the inductive assertion,and it can get solutions of constraint equation directly.
