在同一頁的段落之後浮動

Question

我總是將浮動環境放在首次引用的段落末尾。

但是當段落分為兩頁（從第一頁底部開始到第二頁頂部結束）時，我遇到了問題。浮動可以很容易地放置在第一頁的頂部，因為它是在第一頁上的段落的第一句中直接引用的，即使浮動也在此頁上。但是 Latex 將浮動放在第二頁上，導致第一頁半空（因為現在缺少浮動）和第二頁半空（因為浮動現在是該頁面上唯一的東西）。

有沒有比在段落之前手動移動來源中的浮動環境更簡單的方法（當上述條件不再成立時，例如插入附加文字時，會出現所有問題）？

MWE（第二頁有浮動）

若要重複使用巨集名稱，請第二次使用 \renewcommand。

\documentclass{article}

\usepackage{algorithm2e}
\usepackage[nopar]{lipsum}

\begin{document}
\null\vfill
\lipsum[1-3]

\newcommand{\InsertAlgorithmHere}{%
\begin{algorithm}[tbp]
