Overfull hbox when using enumerate inside algorithm environment

Question

When I tried to use the enumerate environment inside the algorithm environment (algorithm2e package) I got this warning message:

Overfull \hbox (15.0pt too wide) detected at line 13

Here is a minimal working example I used to test the warning:

\documentclass{article}
\usepackage{algorithm2e}

\begin{document}

\begin{algorithm}
    \caption{Test}
        \begin{enumerate}
            \item first item
        \end{enumerate}
    \label{alg:test}
\end{algorithm}

\end{document}

Does anyone know what the problem is and how to solve it?

P.S: I really need to get rid of this warning.

Answer 1

If you want to enumerate lines inside algorithm, don't use a enumerate, but rather the linesnumbered option when you load algorithm2e:

\documentclass{article}

\usepackage[linesnumbered]{algorithm2e}
\DontPrintSemicolon

\begin{document}

\begin{algorithm}
  \caption{Test}
  first item\;
\end{algorithm}

\end{document}
