A genetic algorithm is specially designed to search the rules with avalanche effects in left and right toggle rule space , this kind of rules are sensitive to the initial configuration and reversible as well 本文还采用遗传算法搜索出具有雪崩效应的左右触发规则,这类规则不仅对初始配置极为敏感,同时也具有可逆性。
The aim of this paper is to study the applications of grobner bases in finding the minimal polynomial of a given matrix and its inverse if it is nonsingular and to discuss selfdualities over a polynomial ring ) bner基理论在求矩阵极小多项式，判定矩阵可逆性和求逆矩阵等方面的应用，并讨论了多项式环的分次自对偶问题。
These theorems is the basis and guideline for constructing and verifying the weak derivation set according to the invertibilrty of attribute mapping , thus improves the basic theories of data lineage tracing 这些定理为作者根据属性映射的可逆性构造和验证弱起源集提供了基本依据和指导思想，丰富了数据志跟踪的基本理论。
