latex中插入伪代码

在latex中插入伪代码需要使用的宏有：

\usepackage{multirow}
\usepackage{algorithm}
\usepackage{algpseudocode}
\usepackage{amsmath}
\usepackage[top=2cm, bottom=2cm, left=2cm, right=2cm]{geometry}
\usepackage{algorithmicx}
\usepackage{algpseudocode}


%\floatname{algorithm}{算法}
\renewcommand{\algorithmicrequire}{\textbf{Input:}}
\renewcommand{\algorithmicensure}{\textbf{Output:}}

algorithm1代码如下：

\begin{algorithm}[h]
  \caption{algorithm1}
  \label{your label}
  \begin{algorithmic}[1]
    \Require
      Enter .....;
    \Ensure
      Outpur......
    \State state1......
    \State state2......
    \State state3......
    \While{(a$>$b)}

        \State  state4......
        \If { c$<$d}
            \State state5......
        \Else
            \State state6......
        \EndIf
        \State state7......
    \EndWhile
  \end{algorithmic}
\end{algorithm}

算法3的代码如下：

\begin{algorithm}[h]
  \caption{algorithm1}
  \label{your label}
  \begin{algorithmic}[1]
    \Require
      Enter .....;
    \Ensure
      Outpur......
    \State state1......
    \State state2......
    \State state3......
    \While{(a$>$b)}

        \State  state4......
        \If { c$<$d}
            \State state5......
        \Else
            \State state6......
        \EndIf
        \State state7......
    \EndWhile
    \For{aaa}
        \State state8......
    \EndFor
  \end{algorithmic}
\end{algorithm}
