如何在乳胶中将算法与线宽相匹配

以下算法超出了列的宽度：

\begin{algorithm}[!htb]
\caption{........}
\label{alg:BuildMG} 
%\algsetup{linenosize=\small}

\scriptsize
\DontPrintSemicolon

\SetKwInOut{Input}{input}\SetKwInOut{Output}{output}
\Input{$Path, CV\_LOAD\_IMAGE\_COLOR$\tcc*[f] { ......}\\} 
\Output{$Array~of~Roots$ \tcc*[f] { .........}\\}

\Begin{
    \nl $InvestigateDirSubDir(Path)$\\
    \nl\ForEach{$file$  \tcc*[f] { ............}\\}{
        \nl\If{$Matobject.data$}{       
             \nl $Increment~~NumberOfImages$ \\
             \nl $cvtColor(-,-,CV\_BGR2GRAY)$\\
             \nl $getHeightWidth()$\\            
             \nl $HeadDLL = buildAgrid(height, width)$\\
             \nl $Previous=arrayOfRoots[NumberOfImages\%NumberOfGroups].east$
             \nl $arrayOfRoots[NumberOfImages\%NumberOfGroups].east=HeadDLL$\\          
             \nl $TailDLL = getLastgrid(HeadDLL)$\\
             \nl $TailDLL->south = Previous$\\           
             }           
        }
    }


\end{algorithm}

答案1

根据您的算法变量，除了以下之外您无能为力：

  • 缩短变量名称（同时保持可读性）：
    也许使用ImageNumandGroupNum而不是NumberOfImagesand NumberOfGroups。

  • 减少嵌套结构的水平缩进：
    用于减少垂直\SetInd周围的空间。vlines

换行符合预期，因为您的算法中使用的“单词”没有指定连字符模式。此外，在数学模式中设置所有内容允许断点仅出现在特定位置，例如二元运算符（+例如）或关系（=例如）。

下面的示例试图强调上述两种措施，并为算法的组件建议更合适的格式。为此，它定义了

  • \var{<variable>}设置一个<variable>；

  • \proc{<procedure>}{<arguments>}设置一个<procedure>可能的<arguments>；并且

  • \prop{<property>}设置<property>与变量关联的：

定义宏来处理格式允许您在将来轻松更改此设置。

\SetInd{<before rule space>}{<after rule space>}用于调整第二种算法中v垂直线周围的间距。rules

另一个选择是进一步减小字体大小，但这有点荒谬。最后，您可以将整个算法放在一个框中，然后将其缩小以适合\linewidth。但是，这同样不美观。
