将算法分解成几个部分

在此处输入图片描述

我想将我编写的算法分成几部分，如附件所示

这是我目前所做的：

\begin{algorithm}
\caption{Selection algorithm}
\label{mpral}
\begin{algorithmic}[1]  
\State initialization 
\State ini = $4$ 
\State init = $0$ 
\Procedure {DriftingPhase}{}
\For{each source $S$}
\State Broadcast IWD\textendash 
\For{each IWD}
\vspace{0.05in}
\State \small{Compute soil ($i$,$j$) = $ (1-\Pisymbol{psy}{114}).Soil ($i$, $j$)-\Pisymbol{psy}{114}\Delta Soil($i$, $j$)$}
\vspace{0.01in}
\State Compute $P_{r}$ = ($i$,$j$) = $\frac{f(soil(i,j))}{\sum\nolimits_{k\notin vc(IWD)}{f(soil(i,k)}}$
\State f (soil(i,j)) = $\frac{1}{soil(i,j)}$
\EndFor
\EndFor
\EndProcedure
\Statex
\Procedure{FindingRoute phase}{}
\For{each destination $D$ }
\State MPRset ($D$) = max{$P_{r}$($z$)\textbar\ $z$ $\in$$R$}} 
\State Send IWD\textendash Rep $2$\textendash hop away
\EndFor
\EndProcedure
\Statex
\Procedure{finalPhase}{}
\For{each source $S$ }
\State MPRset ($S$) = max{$P_{r}$($z$)\textbar\ $z$ $\in$$R$}} 
\EndFor
\State MPRRoute= [S] 
\EndProcedure
\end{algorithmic}
\end{algorithm}

这些是使用过的包

\usepackage{algorithm}% http://ctan.org/pkg/algorithms
\usepackage{algpseudocode}

答案1

以下最小示例提供了在算法中\phase{<desc>}设置Phase X - <desc>描述的功能。请注意，它的用法仅在缩进的顶层才按预期工作。但是，我认为这对于算法的呈现来说已经足够了。
