如何在 algorithm2e 中获得结尾

Question

我正在使用 algorithm2e 排版算法。我喜欢下面的外观，但我无法关闭end`

开始

`. 有什么办法吗？

\documentclass{article}
\usepackage[longend,ruled,vlined]{algorithm2e} 

\begin{document}

\begin{algorithm}
    \caption{PHORIZONTAL Algorithm}\label{alg:phorizontal}
\KwIn{$R$: relation; $Pr$: set of simple predicates}
\KwOut{$F_{R}$: set of horizontal fragments of $R$}
    \Begin{
$Pr' \leftarrow $COM\_MIN($R, Pr$) \;
determine the set $M$ of minterm predicates \;
determine the set $I$ of implications among $p_i \in Pr'$ \;
\ForEach{$m_{i} \in M$}{
    \If{ $m_{i}$ is contradictory according to $I$}{$M \leftarrow M - m_{i}$} 
}
$F_{R} = \{R_{i} | \sigma_{m_{i}} R, m_{i} \in M\}, \forall m_{i} \in M$ \;
}
\end{algorithm} 
\end{document} 

Answer 1

参考@egreg 的回答结束词隐藏在算法块中，该vlined选项会抑制“end”的打印。只需删除该选项：

\documentclass{article}
\usepackage[longend,ruled]{algorithm2e}

\begin{document}

\begin{algorithm}
    \caption{PHORIZONTAL Algorithm}\label{alg:phorizontal}
\KwIn{$R$: relation; $Pr$: set of simple predicates}
\KwOut{$F_{R}$: set of horizontal fragments of $R$}
    \Begin{
$Pr' \leftarrow $COM\_MIN($R, Pr$) \;
determine the set $M$ of minterm predicates \;
determine the set $I$ of implications among $p_i \in Pr'$ \;
\ForEach{$m_{i} \in M$}{
    \If{ $m_{i}$ is contradictory according to $I$}{$M \leftarrow M - m_{i}$}
}
$F_{R} = \{R_{i} | \sigma_{m_{i}} R, m_{i} \in M\}, \forall m_{i} \in M$ \;
}
\end{algorithm}
\end{document}
