Document Classes ⇒ algorithm, algorithmic | Remove Rules from Algorithms

[beegii]

Hello,

The example given below is what I want to do. But there are three extra lines.

Code: Select all

\documentclass{article}
\usepackage[noend]{algorithmic} 
\usepackage{algorithm}

\begin{document}
\begin{algorithm}
\caption{Iterate} \label{alg:it}
\begin{algorithmic}
\STATE n = 1
\FOR { $i=1$ \TO $n$ }
   \STATE $print(i)$
\ENDFOR
\end{algorithmic}
\end{algorithm}

\end{document}

So, how to remove those hrule from algorithm package?

Thanks

The algorithm package offers options like "plain", "ruled", "boxed" etc. to specify the float style of the algorithm environment. The default one is "ruled". (The algorithm package uses the float package for this purpose.)

Code: Select all

\documentclass{article}
\usepackage[noend]{algorithmic} 
\usepackage[plain]{algorithm} % NOTE THE "plain" option HERE

\begin{document}
\begin{algorithm}
\caption{Iterate} \label{alg:it}
\begin{algorithmic}
\STATE n = 1
\FOR { $i=1$ \TO $n$ }
   \STATE $print(i)$
\ENDFOR
\end{algorithmic}
\end{algorithm}

\end{document}

Sommerfee thanks for the reply.
OK, I'd like to see the caption is appeared on the top left corner (exactly the same as for the "ruled" option, but without hlines).

Like this?

Code: Select all

\documentclass{article}
\usepackage[noend]{algorithmic} 
\usepackage{algorithm}
\floatstyle{plaintop}
\restylefloat{algorithm}
\usepackage{caption}
\captionsetup[algorithm]{singlelinecheck=off}

\begin{document}
\begin{algorithm}
\caption{Iterate} \label{alg:it}
\begin{algorithmic}
\STATE n = 1
\FOR { $i=1$ \TO $n$ }
   \STATE $print(i)$
\ENDFOR
\end{algorithmic}
\end{algorithm}

\end{document}

For explanation see float and caption package documentation.

Yes, exactly. Thank you very much
