如何減少演算法循環內的縮排大小

Question

對於以下演算法，我為迴圈內的每個文字行取得四個空格。我怎樣才能得到兩個或三個空間？我的一些文字行轉到下一行。我想節省一些水平空間。

\usepackage[noline,boxruled,commentsnumbered,linesnumbered,titlenumbered]{algorithm2e}

\IncMargin{0.5em}
\begin{algorithm}
\SetKwInOut{Input}{input}\SetKwInOut{Output}{output}
\SetKwFor{Foreach}{for each}{do}{endfor}
\SetKwIF{If}{ElseIf}{Else}{if}{then}{else if}{else}{endif}
\BlankLine
\Input{A method \emph{m}}
\Output{result}
\BlankLine
\Foreach { $x \in M_{x}$}{
 do something
}
\caption{Algorithm}\label{Method}
\end{algorithm}

Answer 1

使用

\SetInd{<space before>}{<space after>}

控制垂直線之前和之後的間距（透過此選項停用noline）。以下是預設設定和帶有 的設定的比較\SetInd{0.25em}{0.1em}：

代碼：

\documentclass{article}
\usepackage[noline,boxruled,commentsnumbered,linesnumbered,titlenumbered]{algorithm2e}

\IncMargin{0.5em}
\begin{document}
\noindent
Without setting \verb|\SetInd{}{}|: 
\begin{algorithm}
\SetKwInOut{Input}{input}\SetKwInOut{Output}{output}
\SetKwFor{Foreach}{for each}{do}{endfor}
\SetKwIF{If}{ElseIf}{Else}{if}{then}{else if}{else}{endif}
\BlankLine
\Input{A method \emph{m}}
\Output{result}
\BlankLine
\Foreach { $x \in M_{x}$}{
 do something
}
\caption{Algorithm}\label{Method}
\end{algorithm}

\noindent
With \verb|\SetInd{0.25em}{0.1em}|:
\SetInd{0.25em}{0.1em}
\begin{algorithm}
\SetKwInOut{Input}{input}\SetKwInOut{Output}{output}
\SetKwFor{Foreach}{for each}{do}{endfor}
\SetKwIF{If}{ElseIf}{Else}{if}{then}{else if}{else}{endif}
\BlankLine
\Input{A method \emph{m}}
\Output{result}
\BlankLine
\Foreach { $x \in M_{x}$}{
 do something
}
\caption{Algorithm}\label{Method}
\end{algorithm}
\end{document}
