未定义控制序列。\end{frame} 投影仪算法存在问题

Question

当我尝试在 beamer 中插入算法时，出现错误“未定义的控制序列。\end{frame}”。

\documentclass{beamer}
\usepackage{etex}
\usetheme{Warsaw}
\setbeamercolor {alerted text} {fg=blue}
\logo{\includegraphics[height=.8cm]{NITlogo}}
\usepackage{beamerthemeshadow}
\usepackage{textcomp}
\usecolortheme[RGB={0,153,0}]{structure}
\usecolortheme{crane}
\useinnertheme{rounded}
\usepackage{graphicx,amsmath}
\usepackage{verbatim,longtable}
\hypersetup{pdfpagemode=FullScreen}
\usepackage{verbatim}
\usepackage{pdflscape}
\usepackage{booktabs}
\usepackage{multirow}
\usepackage{array,colortbl,xcolor}

\usepackage{ragged2e}
\usepackage{algorithm}
\usepackage{algorithmic}
\usepackage{subfig}
\newcommand\Fontvi{\fontsize{6}{7.2}\selectfont}
\setbeamertemplate{caption}[numbered]
\setbeamertemplate{frametitle continuation}{}
\usepackage{adjustbox}
\definecolor{deepblue}{RGB}{0,0,128}
\begin{document}
\begin{frame}{}
 \begin{algorithm}[H]
    \caption{Algorithm }\label{alg:alg1}
    \begin{algorithmic}[1]
        \STATE Sink node  
        \STATE Store the value 
        \subitem a\textunderscore value .
        \subitem c\textunderscore value .
        \subitem SINR\textunderscore = .
        \subitem kappa\textunderscore = .
        \STATE Sink node broadcasts 
        \STATE Each .
        \STATE .


    \end{algorithmic}
 \end{algorithm}
\end{frame}

Answer 1

添加后\end{document}，[fragile]MWE 中的错误消息表明\subitem未定义。要解决这个问题，请将其定义为执行输出应该执行的操作 - 在下面我使用了

\newcommand{\subitem}{\par\qquad}

但您可以根据需要进行更改。

您的示例中有一些多余的包：您不需要graphicx或xcolor使用 beamer，因为 beamer 已经提供了此功能。
