LaTeX 算法过长分页显示

1、引用宏包

\usepackage{algorithmic}
\usepackage{algorithm,float}

2、编写可分页的算法格式

\makeatletter
\newenvironment{breakablealgorithm}
{% \begin{breakablealgorithm}
   \begin{center}
     \refstepcounter{algorithm}% New algorithm
     \hrule height.8pt depth0pt \kern2pt% \@fs@pre for \@fs@ruled 画线
     \renewcommand{\caption}[2][\relax]{% Make a new \caption
       {\raggedright\textbf{\ALG@name~\thealgorithm} ##2\par}%
       \ifx\relax##1\relax % #1 is \relax
         \addcontentsline{loa}{algorithm}{\protect\numberline{\thealgorithm}##2}%
       \else % #1 is not \relax
         \addcontentsline{loa}{algorithm}{\protect\numberline{\thealgorithm}##1}%
       \fi
       \kern2pt\hrule\kern2pt
     }
  }{% \end{breakablealgorithm}
     \kern2pt\hrule\relax% \@fs@post for \@fs@ruled 画线
   \end{center}
  }
\makeatother
-----------后面是文章内容----------
\begin{document}......

3、添加算法

\begin{breakablealgorithm}
  \caption{标题}
  \hspace*{0.02in} \raggedright {\bf Input:}  %开头格式、左对齐的Input语句
   Input语句内容 \\                           % 换行符
  \hspace*{0.02in} \raggedright {\bf Output:}
   Output语句内容 \\
  \begin{algorithmic}[1]
    \STATE 算法语句
  \end{algorithmic}
\end{breakablealgorithm}
