求符号网络函数的变形双图分解分析法
MODIFIED DOUBLE-GRAPH DECOMPOSITION ANALYSIS FOR FINDING SYMBOLIC NETWORK FUNCTIONS
-
摘要: 引入了互补余因式对、正规双图和可行撕裂点集的概念。应用它们导出了一阶余因式C(Y)的分解定理。把它与变形双图法相结合,提出了求符号网络函数的一个新的分解分析法变形双图分解分析法。它的优点是所得符号网络函数表达式紧凑而且不含对消项,并且它的符号计算很简单。

Abstract: The concepts of complementary cofactor pairs, normal double-graphs and feasible torn vertex sets are introduced. By using them a decomposition theorem for first-order cofactor C(Y) is derived. Combining it with the modified double-graph method, a new decomposition analysis-modified double-graph decomposition analysis is presented for finding symbolic network functions. Its advantages are that the resultant symbolic expressions are compact and contain no cancellation terms, and its sign evaluation is very... -
