Hello all,

I am using algorithmic to format algorithms, but to get the nice numbering of algorithms and to make references to them I have to put them in floats that is like this

Code: Select all

\begin{algorithm}[htb]
	\caption{Insert($k$)}
	\textbf{Input:} A new key $k$ to insert into the heap. \\
	\textbf{Output:} Nothing. \\
	\textbf{Metode:}
	\begin{algorithmic}[1]
    \State{$Q.add(k)$}
    \If{$Q.size() >= Pm$}
      \State{Rename $l$ to $l+1$ and write the insert buffer $I$ to file $l$}
    \EndIf
    \If{$parent{l+1} \neq parent{l}$}
      \State{$Bubble(l+1)$}
    \EndIf
    \If{$l \neq 0$}
      \State{$Bubble(l)$}
    \EndIf
		\algstore*{Insert}
	\end{algorithmic}
	\label{alg:Insert}
\end{algorithm}

and I do not want them to be floats, but when I do this

Code: Select all

	\begin{algorithmic}[1]
    \State{$Q.add(k)$}
    \If{$Q.size() >= Pm$}
      \State{Rename $l$ to $l+1$ and write the insert buffer $I$ to file $l$}
    \EndIf
    \If{$parent{l+1} \neq parent{l}$}
      \State{$Bubble(l+1)$}
    \EndIf
    \If{$l \neq 0$}
      \State{$Bubble(l)$}
    \EndIf
		\algstore*{Insert}
	\end{algorithmic}

I cannot make references to the code with labes as the environment "algorithmic" does not have any counter.

Then i decided to try and make my own with the following

Code: Select all

\newcounter{algo}
\setcounter{algo}{0}
\newenvironment{algo}[1][]{
  \refstepcounter{algo}
  \makebox[\linewidth]{\line(1,0){\linewidth}}
  \noindent \textbf{Algorithm} #1 \hspace*{\fill} \newline
  \makebox[\linewidth]{\line(1,0){\linewidth}}
  \noindent
}{
  \makebox[\linewidth]{\line(1,0){\linewidth}}
}


See \ref{test}
\begin{algo} %\label{test}
  \begin{algorithmic}[1]
    \State{$Q.add(k)$}
	\end{algorithmic}
\end{algo}
See \ref{test}

which is more or less what I want, the spaceing should be adjusted, but the main problem is that I get tons of warnings, and I do not like that see

Code: Select all

Hi,

since the algorithm environment implemented by the algorithms package (which I guess is the package that you are using) is built with the float package, then you can use the "H" modifier (which means "place this object HERE") to specify the placement; i.e., you can use something like

Code: Select all

\begin{algorithm}[H]
...(some code)
\end{algorithm}
