# How may I create notation for minimisation or maximisation over parameters?

I would like to create notation for minimisation or maximisation over parameters such as the notation shown here:

I have a solution which is very inelegant. What do you think would be the neatest approach to creating this notation in LaTeX?

How about showing this "very inelegant" solution? – Werner Oct 12 '12 at 17:32
The rationale for not showing my solution is to avoid creating bias in the possible answers. My approach involved the use of underset and arrays. – d3pd Oct 12 '12 at 18:09

amsmath has a \substack for this:

\documentclass{article}
\usepackage{amsmath}

\begin{document}

$\min_ {\left\{\substack{ p^{\mathrm{miss}},E^{\mathrm{miss}}\\ (p^{\mathrm{miss}})^2=0} \right\}} [(p^l + p^{\mathrm{miss}})^2]$

\end{document}

This is great. Thank you very much for your assistance. – d3pd Oct 12 '12 at 18:08
