latex伪代码跨栏

要在LaTeX中排列跨越多栏的伪代码,您可以使用`algorithmicx`和`multicol`宏包的组合。以下是一个示例:
```latex
\documentclass{article}
\usepackage{algorithm}
\usepackage{algpseudocode}
\usepackage{multicol}
\begin{document}
\begin{algorithm}
\caption{Example Algorithm}
\begin{multicols}{2}
\begin{algorithmic}[1]
\Procedure{MergeSort}{$A, p, r$}
\If{$p < r$}
\State $q \gets \lfloor (p+r)/2 \rfloor$
\State \Call{MergeSort}{$A, p, q$} \Comment{Sort left half}
\State \Call{MergeSort}{$A, q+1, r$} \Comment{Sort right half}
\State \Call{Merge}{$A, p, q, r$} \Comment{Merge two sorted halves}
\EndIf
\EndProcedure
\\
\Procedure{Merge}{$A, p, q, r$}
\State $n_1 \gets q-p+1$
\State $n_2 \gets r-q$
\State create new arrays $L[1..n_1+1]$ and $R[1..n_2+1]$
\For{$i \gets 1$ to $n_1$}
\State $L[i] \gets A[p+i-1]$
\EndFor
\For{$j \gets 1$ to $n_2$}
\State $R[j] \gets A[q+j]$
\EndFor
\State $L[n_1+1] \gets \infty$
\State $R[n_2+1] \gets \infty$
\State $i \gets 1$
\State $j \gets 1$
\For{$k \gets p$ to $r$}
\If{$L[i] \leq R[j]$}
\State $A[k] \gets L[i]$
\State $i \gets i+1$
\Else
\State $A[k] \gets R[j]$
\State $j \gets j+1$
\EndIf
\EndFor
\EndProcedure
\end{algorithmic}
\end{multicols}
\end{algorithm}
\end{document}
```
这个示例中,我们使用了`multicols`环境将伪代码分为两栏。您可以根据需要调整`multicols`环境中的列数。请确保在您的文档中正确引入`algorithm`,`algpseudocode`和`multicol`宏包。
