编程语言语义中的一个基本问题是何时应将两个程序视为等效。在本文中,我们介绍了 CHR 程序和用户定义的约束的操作等效概念。约束处理规则 (CHR) 是一种高级语言,用于从头开始或通过修改现有求解器来编写约束求解器。
A fundamental question in programming language semantics is when two programs should be considered equivalent. In this paper we introduce a notion of operational equivalence for CHR programs and user-defined constraints. Constraint Handling Rules (CHR) is a high-level language for writing constraint solvers either from scratch or by modifying existing solvers.
