求符號網絡函數的變形雙圖分解分析法
MODIFIED DOUBLE-GRAPH DECOMPOSITION ANALYSIS FOR FINDING SYMBOLIC NETWORK FUNCTIONS
-
摘要: 引入了互補余因式對、正規(guī)雙圖和可行撕裂點集的概念。應用它們導出了一階余因式C(Y)的分解定理。把它與變形雙圖法相結合,提出了求符號網絡函數的一個新的分解分析法變形雙圖分解分析法。它的優(yōu)點是所得符號網絡函數表達式緊湊而且不含對消項,并且它的符號計算很簡單。

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... -
