1、注释掉默认的引用
% \usepackage{algorithmic}
% \usepackage{algorithm}
2、在\begin{document}之前加以下内容
\usepackage[ruled,norelsize,vlined,linesnumbered]{algorithm2e}
\makeatletter
\newcommand{\removelatexerror}{\let\@latex@error\@gobble}
\makeatother
3、写具体的算法
\begin{figure}[!t]\label{alg:LSB}\renewcommand{\algorithmicrequire}{\textbf{Input:}}\renewcommand{\algorithmicensure}{\textbf{Output:}}\removelatexerror\begin{algorithm}[H]\caption{algorithm caption}%算法名字\LinesNumbered %要求显示行号\KwIn{input parameters A, B, C}%输入参数\KwOut{output result}%输出some description\; %\;用于换行\For{condition}{only if\;\If{condition}{1\;}}\While{not at end of this document}{if and else\;\eIf{condition}{1\;}{2\;}}\ForEach{condition}{\If{condition}{1\;}}\end{algorithm}\end{figure}
4、效果
