并列放置两种算法

并列放置两种算法

我想将两种算法并排放在文档中,但是当我使用\documentclass{llncs}而不是 时\documentclass{article},以下代码不起作用(错误):

\documentclass{article}
\usepackage[margin=1in]{geometry}% http://ctan.org/pkg/geometry
\usepackage{lipsum}% http://ctan.org/pkg/lipsum
\usepackage{algorithm}% http://ctan.org/pkg/algorithm
\usepackage{algpseudocode}% http://ctan.org/pkg/algorithmicx
\usepackage{caption}% http://ctan.org/pkg/caption
\begin{document}
\lipsum[1]

\medskip

\noindent\begin{minipage}{.5\textwidth}
\captionof{algorithm}{Euclid’s algorithm}\label{algo1}
\begin{algorithmic}[1]
  \Procedure{Euclid}{$a,b$}\Comment{The g.c.d. of a and b}
    \State $r\gets a\bmod b$
    \While{$r\not=0$}\Comment{We have the answer if r is 0}
      \State $a\gets b$
      \State $b\gets r$
      \State $r\gets a\bmod b$
    \EndWhile
    \State \textbf{return} $b$\Comment{The gcd is b}
  \EndProcedure
\end{algorithmic}
\end{minipage}%
\begin{minipage}{.5\textwidth}
\captionof{algorithm}{Euclid’s algorithm}\label{algo2}
\begin{algorithmic}[1]
  \Procedure{Euclid}{$a,b$}\Comment{The g.c.d. of a and b}
    \State $r\gets a\bmod b$
    \While{$r\not=0$}\Comment{We have the answer if r is 0}
      \State $a\gets b$
      \State $b\gets r$
      \State $r\gets a\bmod b$
    \EndWhile
    \State \textbf{return} $b$\Comment{The gcd is b}
  \EndProcedure
\end{algorithmic}
\end{minipage}

On the left is Algorithm~\ref{algo1}. On the right is Algorithm~\ref{algo2}.

答案1

问题在于类文件定义了标题命令,而caption包讨厌它。

caption作为和的软件包作者subcaption,Alex Sommerfeldt 在这个答案中提到了这个问题子字幕包:兼容性问题再次出现与另一个类文件相关的问题。

\captionsetup{compatibility=false}

会使问题消失,但如果类文件对标题设置很挑剔,可能会引入其他问题。

我已经为算法提出了另一种解决方案,但不确定这是否是你想要的:第一个区别是我使用了subcaption包而不是迷你页面。然后我制作了一个简单的subalgorithm环境。并将它们放在一个浮动中(一个表格,但如果需要,也可以是一个涉及计数器的图形)。
