# [Tex/LaTex] algorithm2e, if-then-else alignment in output block

algorithm2e

I would like to have an if-then-else statement in the output block, with this MWE:

\documentclass{article}
\usepackage[ruled]{algorithm2e}
\usepackage{amsmath}

\begin{document}
\begin{algorithm}[H]
\SetKwInput{Output}{Output}
\Output{
\eIf{QP is feasible}{
$x^*$: primal solution of problem (1)\newline
$\lambda^*$: dual solution solving (2).
}{
infeasibility status.
}
}
\caption{QP solver}
\end{algorithm}

\end{document}


i get the following result:

Is there a way of getting the lines of the if-then-else block aligned with the first if if?

Like this:

Thanks!

If you only want what you show, then you can adjust \algomargin:

\documentclass{article}

\usepackage[ruled]{algorithm2e}
\DontPrintSemicolon

\begin{document}

% Update \algomargin
\settowidth{\algomargin}{\textbf{Output:} }
\begin{algorithm}[H]
\makebox[0pt][r]{\textbf{Output:} }%
\eIf{QP is feasible}{
$x^*$: primal solution of problem (1)\;
$\lambda^*$: dual solution solving (2)\;
}{
infeasibility status\;
}
\caption{QP solver}
\end{algorithm}
\setlength{\algomargin}{\parindent}% Restore \algomargin

\begin{algorithm}[H]
\SetKwInOut{Output}{Output}
\Output{\eIf{QP is feasible}{
$x^*$: primal solution of problem (1)\;
$\lambda^*$: dual solution solving (2)\;
}{
infeasibility status\;
}}
\caption{QP solver}
\end{algorithm}

\end{document}


The second algorithm is merely for reference of the alignment.
