伪代码 Latex

Question

如何在 Latex 中编写该算法伪代码：

Algorithm 1  Channel Assignment using Random Ordering (RO)
    K←Set of channels
    C(v)←0,∀v∈V
    root← Root Selection(V)
    C(root)← Channel Selection(root,K)  
    Permutate(V\\{root})
    while  (V!=Empty)
                  v← Removehead(V)
                  C(v)←Channel Selection (v,K) 
         V←V−1
    end while
    Return(C)

Answer 1

下面是使用伪代码实现的算法algorithm2e：

\documentclass{article}
\usepackage{amsmath}
\usepackage[ruled,longend]{algorithm2e}
\begin{document}
\begin{algorithm}
  $K \gets \text{Set of channels}$\;
  $C(v) \gets 0,\forall v \in V$\;
  $\text{root} \gets \text{Root Selection}(V)$\;
  $C(\text{root}) \gets \text{Channel Selection}(\text{root},K)$\;
  $\text{Permutate}(V,\text{root})$\;
  \While{$V \neq \emptyset$}
  {
    $v \gets \text{Removehead}(V)$\;
    $C(v) \gets \text{Channel Selection}(v,K)$\;
    $V \gets V-1$\;
  }
  \KwRet{$C$}\;
  \caption{Channel Assignment using Random Ordering (RO)}
\end{algorithm}
\end{document}
