连续函数的不动点是指称语义的一个重要内容,它刻画了程序的计算性质.本文对完全偏序、连续函数和不动点等概念及其意义作出直观的解释,介绍了最小不动点的构造和逼近求解方法.
The fixed point of continuous function is an important content in denotational semantics,which specifies the computing properties of programs.In this paper,the intuition behind complete partial order,continuous function and fixed point are presented;the construction of the least fixed point and its approximating solution are introduced.
