LaTeX如何插入算法

1、首先引入几个需要用到的包\usepackage{algorithm} %format of the algorithm\usepackage{algorithmic} %format of the algorithm\usepackage{multirow} %multirow for format of table\usepackage{amsmath}\usepackage{xcolor}

2、重新定义require和ensure命令对应的关键字(此处将默认的Require/Ensure自定义为Input/Output)

3、\renewcommand{\algorithmicrequire}{\textbf{Input:}}\renewcommand{\algorithmicensure}{\textbf{Output:}}

4、分析一下示例：\begin{algorithm} %算法开始\caption{Sample algorithm} %算法的题目\label{alg1} %算法的标签\begin{algorithmic}[1] %此处的[1]控制一下算法中的每句前面都有标号\REQUIRE Text:Today is a good day. Variables:$u,v,w$. $G=(V,E)$ %输入条件(此处的REQUIRE默认关键字为Require，在上面已自定义为Input)

5、\ENSURE Something... %输出结果(此处的ENSURE默认关键字为Ensure在上面已自定义为Output)% if-th髫潋啜缅en-else\IF{some condition is true}\STATE do some processing\ELSIF{some other condition is true}\STATE do some different processing\ELSE\STATE do the default actions\ENDIF% for loop\FOR{$i=0$ to $10$}\STATE carry out some processing

6、\ENDFOR\FORALL{$i$ such that $0\leq i\leq 10$娅势毁歹}\STATE carry out some processing概嗤先眚\ENDFOR% while-loop\WHILE{some condition holds}\STATE carry out some processing\ENDWHILE% repeat-until loop\REPEAT\STATE carry out some processing\UNTIL{some condition is met}% infinite loop\LOOP\STATE this processing will be repeated forever\ENDLOOP\end{algorithmic}\end{algorithm}
