IEEE的Latex模板中使用algorithm

用IEEE的模板寫論文時在算法流程圖這卡住了，和一般的algorithm不同，需要\begin{figure} ， 這裏貼幾個可用的模板

\usepackage{algorithmic}

\makeatletter
\newcommand{\removelatexerror}{\let\@latex@error\@gobble}
\makeatother

	\begin{figure}[!t]
	\label{alg:LSB}
	\renewcommand{\algorithmicrequire}{\textbf{Input:}}
	\renewcommand{\algorithmicensure}{\textbf{Output:}}
	\removelatexerror
	\begin{algorithm}[H]
		\caption{Local Search Based Algorithm}
		\begin{algorithmic}[1]
			\REQUIRE Candidate set $\mathbb{S}$, Initial set $\mathbb{X} = \varnothing$          %%input
			\ENSURE Optimum set $\mathbb{X}$  %%output
			\STATE {set $r(t)=x(t)$}   

		\end{algorithmic}
	\end{algorithm}
\end{figure}
