\def\SetClass{article}
\documentclass{\SetClass}
\usepackage[ruled,linesnumbered]{algorithm2e}
\begin{document}
\begin{algorithm}
\caption{Simulation-optimization heuristic}\label{algorithm}
\KwData{current period $t$, initial inventory $I_{t-1}$, initial capital $B_{t-1}$, demand samples}
\KwResult{Optimal order quantity $Q^{\ast}_{t}$}
$r\leftarrow t$\;
$\Delta B^{\ast}\leftarrow -\infty$\;
\While{$\Delta B\leq \Delta B^{\ast}$ and $r\leq T$}{$Q\leftarrow\arg\max_{Q\geq 0}\Delta B^{Q}_{t,r}(I_{t-1},B_{t-1})$\;
$\Delta B\leftarrow \Delta B^{Q}_{t,r}(I_{t-1},B_{t-1})/(r-t+1)$\;
\If{$\Delta B\geq \Delta B^{\ast}$}{$Q^{\ast}\leftarrow Q$\;
$\Delta B^{\ast}\leftarrow \Delta B$\;}
$r\leftarrow r+1$\;}
