为了向 Chaos 屈服，我下载了Latex 模板AIP 请求。但是当我要插入如下伪代码时
\begin{algorithm}
%\textsl{}\setstretch{1.8}
\renewcommand{\algorithmicrequire}{\textbf{Input:}}
\renewcommand{\algorithmicensure}{\textbf{Output:}}
\caption{STVMD based on STFT}
\label{alg1}
\begin{algorithmic}[1]
\STATE Initialization:$\left\{ {s_{k,t}^1} \right\},\left\{ {\omega _{k,t}^1} \right\},\lambda _t^1,n \leftarrow 0$
\STATE ${s_{r,t}}\left( \omega \right) = \int_0^{ + \infty } {{s_r}\left( \tau \right){w_h}\left( {t - \tau } \right)} \exp \left( {j\omega \tau } \right)d\tau $ (via STFT)
\REPEAT
\STATE $n \leftarrow n + 1$
\STATE Update $ s_{k,t}^{n + 1} $ based on Equation~(\ref{eqn_8})
\STATE Update $\omega _{k,t}^{n + 1}$ based on Equation~(\ref{eqn_9})
\STATE Update $\lambda _t^{n + 1} $ based on Equation~(\ref{eqn_10})
\UNTIL $\sum\limits_{k=1}^P {{{\left\| {s_{k,t}^{n + 1}\left( \omega \right) - s_{k,t}^n\left( \omega \right)} \right\|_2^2} \mathord{\left/
{\vphantom {{\left\| {s_{k,t}^{n + 1}\left( \omega \right) - s_{k,t}^n\left( \omega \right)} \right\|_2^2} {\left\| {s_{k,t}^n\left( \omega \right)} \right\|_2^2}}} \right.
\kern-\nulldelimiterspace} {\left\| {s_{k,t}^n\left( \omega \right)} \right\|_2^2}}} < \varepsilon $
\STATE Update ${s_k}\left( t \right)$ based on Equation~(\ref{eqn_11_12}) (via ISTFT)
\ENSURE decomposed modes $ \left\{ {{s_k}\left( t \right)} \right\}$, $\left\{ {{\omega _k}\left( t \right)} \right\}$
\end{algorithmic}
\end{algorithm}
但编译时抛出了奇怪的错误：
! Missing \endcsname inserted.
<to be read again>
\c@float@type
l.123 \end{algorithm}
The control sequence marked <to be read again> should
not appear between \csname and \endcsname.
! Missing number, treated as zero.
<to be read again>
\endcsname
l.123 \end{algorithm}
A number should have been here; I inserted `0'.
(If you can't figure out why I needed to see a number,
look up `weird error' in the index to The TeXbook.)
! Extra \endcsname.
<recently read> \endcsname
l.123 \end{algorithm}
I'm ignoring this, since I wasn't doing a \csname.
(./aipsamp.bbl
简而言之! 缺少插入 \endcsname。，!缺失数字，视为零。和!缺失数字，视为零。
我搜索了整个互联网，但没有找到解决此错误的办法，任何人都可以帮忙AIP LaTex 模板中的伪代码？ 多谢。

根据回答，你可能需要在 \begin{algorithm} 之后使用 [H]（大写 H！）
