将算法环境直接放在章节/小节下

Question

算法环境放置错误，不在我想要的位置（直接在子节语句下）。我知道关于这个问题的流行答案，比如像图形那样使用float包和参数，但我试过了，它再次失败了，在前面，但在代码中它应该在后面[H]Algorithm 2subsection 2.2

附言：我float现在有包含的包裹

Answer 1

添加 \usepackage{placeins}到您的序言中并更改您的第二个算法如下：

\begin{algorithm}[ht!] % do not use H <<<<
    \caption{Generate set of Terminal nodes.}
    \begin{algorithmic}[1]
        \State \textbf{Inputs:} Set of nodes $L$.
        \State \textbf{Outputs:} Set of terminal nodes $T$.
        \State Create queue $Q$
        \State Create list $T$
        \For {each node $x$ in $L$}
        \State $Q \leftarrow x$
        \While{queue $Q$ in not empty}
        \State $currentNode \leftarrow \mathrm{dequeue \; from \; Q}$
        \If {$currentNode \; \mathrm{is \; terminal \; node}$}
        \State $T \leftarrow currentNode$
        \State $continue$
        \EndIf
        \For {each node $s$ in $currentNode$ child nodes}
        \State $Q \leftarrow s$
        \EndFor
        \EndWhile
        \EndFor
    \end{algorithmic}
\end{algorithm}
 \FloatBarrier% add to the end<<<<<<<<<<<

amsart问题在于定义的方式subsection。参见在 AMS 文档类中用 \subsection 交换材料

正如您在第一小节中看到的，现在\subsection创建了一个运行标题。

选项 2重新定义子节。添加到你的序言中

  \makeatletter
  \renewcommand\subsection{\@startsection{subsection}{2}{\z@}%
        {.5\linespacing\@plus.7\linespacing}
        {0.5ex \@plus .2ex}%
    {\normalfont\bfseries}}
  \makeatother

你会得到
