翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Weight (strings) ： ウィキペディア英語版 Weight (strings) The $a$-weight of a string, for $a$ a letter, is the number of times that letter occurs in the string. More precisely, let $A$ be a finite set (called the ''alphabet''), $a\backslash in\; A$ a ''letter'' of $A$, and $c\backslash in\; A^$ * a ''string'' (where $A^$ * is the free monoid generated by the elements of $A$, equivalently the set of strings, including the empty string, whose letters are from $A$). Then the $a$-''weight'' of $c$, denoted by $\backslash mathrm\_a(c)$, is the number of times the generator $a$ occurs in the unique expression for $c$ as a product (concatenation) of letters in $A$. If $A$ is an abelian group, the Hamming weight $\backslash mathrm(c)$ of $c$, often simply referred to as "weight", is the number of nonzero letters in $c$. == Examples == * Let $A=\backslash$. In the string $c=yxxzyyzxyzzyx$, $y$ occurs 5 times, so the $y$-weight of $c$ is $\backslash mathrm\_y(c)=5$. * Let $A=\backslash mathbf\_3=\backslash$ (an abelian group) and $c=002001200$. Then $\backslash mathrm\_0(c)=6$, $\backslash mathrm\_1(c)=1$, $\backslash mathrm\_2(c)=2$ and $\backslash mathrm(c)=\backslash mathrm\_1(c)+\backslash mathrm\_2(c)=3$. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Weight (strings)」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
