LaTeX 写作： 算法代码排版 --latex2e范例总结

latex2e 宏包的使用范例：

• \usepackage[ruled]{algorithm2e}                                     %算法排版样式1
• \usepackage[ruled,vlined]{algorithm2e}                          %算法排版样式2
• \usepackage[linesnumbered,boxed]{algorithm2e}        %算法排版样式3

使用上述代码中三种不同的宏包编译后的代码排版样式预览：

    How to use the algorithm2e in \LaTeX ~ file.

    Examples: 
%    ------------------------------Example - ---------------------------------------------
        \begin{algorithm}[H]
            \caption{How to write algorithms}
            \KwIn{this text}
            \KwOut{how to write algorithm with \LaTeX2e }

            initialization\;
            \While{not at end of this document}{
                read current\;
                \eIf{understand}
                {
                        go to next section\;
                        current section becomes this one\;
                }
                {
                    go back to the beginning of current section\;
                }
        }
    \end{algorithm}

%    ---------------------------Example - ------------------------------------------------
    \begin{algorithm}
%    \SetAlgoNoLine  %去掉之前的竖线
     \caption{identifyRowContext}
      \KwIn{$r_i$, $Backgrd(T_i)$=${T_1,T_2,\ldots ,T_n}$ and similarity threshold $\theta_r$}
      \KwOut{$con(r_i)$}
        $con(r_i)= \Phi$\;
        \For{$j=;j \le n;j \ne i$}
        {
            float $maxSim=$\;
            $r^{maxSim}=null$\;
            \While{not end of $T_j$}
            {
                compute Jaro($r_i,r_m$)($r_m\in T_j$)\;
                \If{$(Jaro(r_i,r_m) \ge \theta_r)\wedge (Jaro(r_i,r_m)\ge r^{maxSim})$}
                {
                    replace $r^{maxSim}$ with $r_m$\;
                }
            }
            $con(r_i)=con(r_i)\cup {r^{maxSim}}$\;
        }
        return $con(r_i)$\;
    \end{algorithm}
    %--------------------------------------------------------------------------------------
 some special information
    The algorithm2e LaTeX package conflicts with several others over the use of the algorithm identifier.  A common indicator is something like this message:
To resolve the issues, simply put the following just before the inclusion of the algorithm2e package:

%\makeatletter
%\newif\if@restonecol
%\makeatother
%\let\algorithm\relax
%\let\endalgorithm\relax

\end{document}

中文latex模式下，更改Input为输入，更改Output为输出的方法： 在算法内部插入、

\SetKwInOut{KIN}{输入}

\SetKwInOut{KOUT}{输出}

用我们定义的新的宏名“\KIN” 在算法开头相应位置替换掉自带的\KwInput，用"\KOUT" 替换掉\KwOutput 即可，实现中文的输入和输出.

具体事例如下：

 \renewcommand{\algorithmcfname}{算法}
 \begin{algorithm}[H]
 %\SetAlgoNoLine
 4 \SetKwInOut{KIN}{输入}
 5 \SetKwInOut{KOUT}{输出}
 %\BlankLine  %空一行
     \caption{标准DE算法 }
     \label{DE_algo} %
     \KIN{Population: $ M$; Dimension: $ D $; Genetation: $ T $ }
     \KOUT{The best vector (solution)  $ \varDelta $ }
     $ t \leftarrow  (initialization) $\;
     \For{$i=$ to $ M $    }
     {\For{$j=$ to $ D $}
         {
             $  {x}_{i,t}^j=x_{min}^j + rand(,)\cdotp (x_{max}^j-x_{min}^j) $\;
         }
     }
     %--------------------------------------------------
 \While{$(|f(\varDelta)| \geq\varepsilon )$      or     $(t \leq T )$}
     {
         \For{$ i=$  to $M$}
         {
 \emph{$ \blacktriangleright $ (Mutation and Crossover)}\\
 %\textit{ $ \blacktriangleright $ (Mutation and Crossover) }\\
             \For{$j=$ to $ D $}
             {
                 $ v_{i,t}^j =Mutation(x_{i,t}^j)$\;
                 $ u_{i,t}^j =Crossover(x_{i,t}^j,v_{i,t}^j)$\;
             }
 \emph{$ \blacktriangleright $ (Greedy Selection)}\\
             %\textit{ $ \blacktriangleright $ (Greedy Selection) }\\
             \eIf{$ f(\textbf{u}_{i,t}) <  f(\textbf{x}_{i,t}) $}
             {
                 $  \textbf{x}_{i,t} \leftarrow\textbf{u}_{i,t}$\;
                 \If{$  f(\textbf{x}_{i,t}) < f(\varDelta)$}
                 {
                     $ \varDelta \leftarrow \textbf{x}_{i,t}$ \;
                 }
             }
             {
                 $  \textbf{x}_{i,t} \leftarrow \textbf{x}_{i,t} $\;
             }
         }
         $ t \leftarrow t+ $\;
     }    %While
     \Return the best vector  $\varDelta$\;
 \end{algorithm}
