摘要
对称函数有许多优点,引入部分变量取反的对称函数可以大大增加对称函数的数目,从而有助于扩大对称函数的应用范围.检测对称函数是函数对称性研究中的重要工作.分析了基于表格法的对称函数检测,在此基础上进一步提出了改进的部分变量取反的对称函数检测的新方法.
Symmetric functions have many advantages. Introduction of symmetric fuctions with partial negated variables can tremendously increase symmetric function amount,thus making for the range of symmetric function application.The detection of symmetric function is of importance in the research of symmetry .A method for detecting symmetric functions based on tabular method is analyzed.Based upon it, the method of detecting symmetric functions with negation of partial is presented.
