Document Classes ⇒ algorithm / algorithmic: pagebreak

[MacCowboy]

Hi there,

I'd highly appreciate it, if somebody can help me on this one.

I used the algorithm/algorithmic package for a pseudo code.
The issue is that the pseudo code is longer than one page.
Now I get an LaTeX warning: Float too large for page...
I see algorithm uses float..

I wasn't able to find anything online that would address this problem.
I get a page break in the pseudo code when I use algorithmic without algorithm, but than
I have no caption/reference.
Is there any way to get an page break within algorithm? or some kind of float break?

thx

Hi,

in the following minimum working example I define a new environment breakalgo which takes one optional and one mandatory argument. Argument one is the label and argument two the caption. But beware, it is a quite dirty hack and has not been tested profoundly.

Code: Select all

\documentclass[english]{article}
\usepackage{%
  babel,
  blindtext,
  algorithmic,
  algorithm,
  caption
}
\def\source{%
  \REQUIRE $n \geq 0$
  \ENSURE $y = x^n$
  \STATE $y \Leftarrow 1$
  \STATE $X \Leftarrow x$
  \STATE $N \Leftarrow n$
  \WHILE{$N \neq 0$}
    \IF{$N$ is even}
      \STATE $X \Leftarrow X \times X$
      \STATE $N \Leftarrow N / 2$
    \ELSE[$N$ is odd]
      \STATE $y \Leftarrow y \times X$
      \STATE $N \Leftarrow N - 1$
    \ENDIF
  \ENDWHILE
}
\makeatletter
\newenvironment{breakalgo}[2][alg:\thealgorithm]{%
  \def\@fs@cfont{\bfseries}%
  \let\@fs@capt\relax%
  \par\noindent%
  \medskip%
  \rule{\linewidth}{.8pt}%
  \vspace{-3pt}%
  \captionof{algorithm}{#2}\label{#1}%
  \vspace{-1.7\baselineskip}%
  \noindent\rule{\linewidth}{.4pt}%
  \vspace{-1.3\baselineskip}%
}{%
  \vspace{-.75\baselineskip}%
  \rule{\linewidth}{.4pt}%
  \medskip%
}
\makeatother
\begin{document}
  \listofalgorithms
  \blindtext
  \begin{algorithm}
    \caption{Some clever name}
    \begin{algorithmic}
      \source
    \end{algorithmic}
  \end{algorithm}
  \blindtext
  \begin{breakalgo}{Another clever name}%
    \begin{algorithmic}
      \source
    \end{algorithmic}
  \end{breakalgo}
  \blindtext
\end{document}
