Disable the numbering of algorithms

posting working examples would be a nice idea ... ;-) Now only page references make sense:

\documentclass{article}
\usepackage[noend]{algorithmic} 
\usepackage{algorithm,caption}
\algsetup{indent=2em} 
\renewcommand{\algorithmiccomment}[1]{\hspace{2em}// #1} 

\begin{document}
\begin{algorithm}
\caption*{MyAlgorithm} \label{alg:MyAlgorithm}
\begin{algorithmic}[1]
\item foo
\end{algorithmic}
\end{algorithm}

see algorithm on Page~\pageref{alg:MyAlgorithm}
\end{document}

Setting the counter to nothing also works fine

\renewcommand{\thealgorithm}{}

The algorithm name and number are set as a combination. In general this is inside the "float macro" called \fnum@<float>. In the case of algorithm we see this definition for \fnum@algorithm:

> \fnum@algorithm=macro:
->\fname@algorithm {} \thealgorithm .

We can redefine this to only use \fname@algorithm (and therefore drop \thealgorithm - the algorithm numbering):

\documentclass{article}

\usepackage{algorithm,algpseudocode}

\makeatletter
\renewcommand{\fnum@algorithm}{\fname@algorithm}
\makeatother

\begin{document}

\begin{algorithm}
  \caption{MyAlgorithm}
  \begin{algorithmic}[1]
    \State An item
  \end{algorithmic}
\end{algorithm}

\end{document}

A similar interface/option is provided using the caption package:

\usepackage{caption}
\DeclareCaptionLabelFormat{algnonumber}{Algorithm}
\captionsetup[algorithm]{labelformat=algnonumber}
