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:

                        current section becomes this one\;

                {

    \begin{algorithm}

     \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{$j=1;j \le n;j \ne i$} 
        { 
            float $maxSim=0$\; 
$r^{maxSim}=null$\; 
            \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
