algorithm2e 的标题位于左上角，无规则选项

Question

我不想使用ruled选项，但我仍然希望我的算法的标题位于左上角。

我试过

\renewcommand{\@algocf@capt@plain}{above}

但它只会移动上面的标题，而不是左边的标题。

示例输出：

当我使用时\TitleOfAlgo，该行算法 1已编号。

Answer 1

使用此ruled选项，整个算法块上方/下方的水平规则的高度为\algoheightrule，而标题和算法之间的规则的高度为\algotitleheightrule。 将这些设置为0pt会删除规则，但仍保持相同的ruled类似格式：

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

\begin{document}

\begin{algorithm}[H]
  \SetAlgoLined
  \KwData{this text}
  \KwResult{how to write algorithm with \LaTeX2e }
    initialization\;
  \While{not at end of this document}{
    read current\;
    \eIf{understand}{
      go to next section\;
      current section becomes this one\;
    }{
      go back to the beginning of current section\;
    }
  }
  \caption{How to write algorithms}
\end{algorithm}

\setlength{\algoheightrule}{0pt}
\setlength{\algotitleheightrule}{0pt}

\begin{algorithm}[H]
  \SetAlgoLined
  \KwData{this text}
  \KwResult{how to write algorithm with \LaTeX2e }
    initialization\;
  \While{not at end of this document}{
    read current\;
    \eIf{understand}{
      go to next section\;
      current section becomes this one\;
    }{
      go back to the beginning of current section\;
    }
  }
  \caption{How to write algorithms}
\end{algorithm}

\end{document}
