乳胶中的并排算法

Question

我正在使用“elsarticle”类，需要并排放置两个算法。我正在使用 minipage 功能来执行此操作，但算法并没有完全并排生成（附上图片供您参考）。工作乳胶代码如下：

documentclass[3p]{elsarticle}
\usepackage{hyperref}
%\modulolinenumbers[5]
\usepackage[ruled,linesnumbered]{algorithm2e}
\usepackage{amsfonts}
\usepackage{threeparttable}

\usepackage{mathtools}
\DeclarePairedDelimiter\ceil{\lceil}{\rceil}
\usepackage{caption}

\begin{document}

    \caption{ $ZADDU_{(X,Y)}$}          
    
    \label{alg1}   
    %\begin{multicols}{2}                       % and a label for \ref{} commands 
    \begin{algorithmic}[1] 
    \Require{ $R_1 = (X_1, Y_1, Z )$ and $R_2 = (X_2, Y_2, Z)$ }
    \Ensure {$(R_3, R_1)\mspace{5mu} = \mspace{5mu}ZADDU_{(X,Y)}(R_1, R_2)$ $\mspace{15mu}$where $R_3= R_1 + R_2=
(X_3, Y_3, Z_3)$ and $R_1 = (\lambda^2{X_1}, \lambda^3 {Y_1}, Z_3)$  with $Z_3=\lambda Z$ for some $\lambda\neq0$}\\
%   \tcc{\textbf{Phase A:}}
%   $z := 0, R_1 := x$\;
%   $R_2 := u_2$\; 
%   
%   \tcc{\textbf{Phase B:}}
$B=(X_1-X_2)^2$; 
    $E_1 =X_1 U; E_2 = X_2 U$; $C =(Y_1 - Y_2)^2$\\
      $D =Y_1 (E_1 - E_2)$; $X_3=C - E_1 - E_2$; 
      $Y_3=(Y_1 - Y_2)(E_1 - X_3 ) - D$;\\
       ${X_1}=  E_1$; ${Y_1} = D$; 
     $R_3=(X_3, Y_3)$, $R_3=(X_1, Y_1)$\\
    \Return{($R_3,R_1$)}\;
    \end{algorithmic}
\end{algorithm}
\end{minipage}
\hfill
\begin{minipage}{0.5\textwidth}
\begin{algorithm}[H]
%        \caption{(X,Y)-only  conjugate co-Z addition ($ZADDC_{(X,Y)}$)}              
    \caption{$ZADDC_{(X,Y)}$}          
    % give the algorithm a caption
    \label{alg1}   
    %\begin{multicols}{2}                       % and a label for \ref{} commands 
    \begin{algorithmic}[1] 
    \Require{ $R_1 = (X_1, Y_1, Z )$ and $R_2 = (X_2, Y_2, Z)$ }
    \Ensure {$(R_3, \overline R_3)\mspace{5mu} = \mspace{5mu}ZADDC_{(X,Y)}(R_1, R_2)$$\mspace{10mu}$where $R_3= R_1 + R_2=
(X_3, Y_3, Z_3)$ and $\overline R_3 =R_1 - R_2= (\overline{X_3},\overline {Y_3}, Z_3)$ }\\
%   \tcc{\textbf{Phase A:}}
%   $z := 0, R_1 := x$\;
%   $R_2 := u_2$\; 
%   
%   \tcc{\textbf{Phase B:}}
$B=(X_1-X_2)^2$;  
    $E_1 =X_1 U; E_2 = X_2 U$; $C =(Y_1 - Y_2)^2$;\\
      $D =Y_1 (E_1 - E_2)$; $X_3=C - V_1 - V_2$;
      $Y_3=(Y_1 - Y_2)(E_1 - X_3 ) - D$; \\
     $\overline{C} = (Y1 + Y2)^2$;  $\overline{X_3}=  \overline{C} - E_1 - E_2$; $\overline{Y_3} = (Y_1 + Y_2)(E_1 - \overline{X_3} ) - D$;\\
    
    \Return{($R_3,\overline R_3$)}\;
    \end{algorithmic}
 \end{algorithm}
 \end{minipage}

附上一张输出图片，如果能帮助您并排对齐这些算法，我们将不胜感激。
