如何在投影仪中添加算法？

Question

我正在尝试在我的 beamer 演示文稿中添加算法伪代码，只需复制并粘贴我在撰写论文时使用的代码，如下所示：

\documentclass{beamer}
\mode<presentation> { 
\usetheme{Madrid} 
}

\usepackage{graphicx} % Allows including images
\usepackage{booktabs} % Allows the use of \toprule, \midrule and \bottomrule in tables
\usepackage{biblatex}
\usepackage{xcolor}
\usepackage{algorithm,algorithmic}  

\begin{document}
\begin{frame}[fragile]
\begin{algorithm}[H]
    \caption{Text Summarization Algorithm}\label{euclid}
    \begin{algorithmic}[1]
        \Procedure{Summary Construction}{}\newline
        \textbf{Input:} Text Document.\newline
        \textbf{Output:} Summary sentences.
        \State{Creating information table from a text document.}
        \State{Generate matrices.}
        \State {\textbf{Call Pocedure:} Reduct Construction \textbf{[Algorithm 2]}}
        \State {\textbf{Return:} Summary sentences}
        \EndProcedure
    \end{algorithmic}
    \label{alg_1}
\end{algorithm}
\end{frame}

\end{document}

我得到的错误是Undefined control sequence. \end{frame}。如果有人能帮助我解决这个问题，我将不胜感激。

请提供完整的最小示例。这在 TeX Live 2015 下编译得很好。

\documentclass[a4paper]{beamer}
\usepackage{algorithm,algpseudocode}
\begin{document}


\begin{frame}
\begin{algorithm}[H]
    \caption{Text Summarization Algorithm}\label{euclid}
    \begin{algorithmic}[1]
        \Procedure{Summary Construction}{}\newline
        \textbf{Input:} Text Document.\newline
        \textbf{Output:} Summary sentences.
        \State{Creating information table from a text document.}
        \State{Generate matrices.}
        \State {\textbf{Call Pocedure:} Reduct Construction \textbf{[Algorithm 2]}}
        \State {\textbf{Return:} Summary sentences}
        \EndProcedure
    \end{algorithmic}
    \label{alg_1}
\end{algorithm}
\end{frame}

\end{document}
