花了 2 小时尝试了各种方法后，我放弃了。我正在使用algorithm2e，当我有较长的描述行时，新行会稍微向右移动。此外，即使我在两个段落之间添加了新的空行，输出中也不会显示空行。
首先，这是问题的图表，下面是生成该问题的代码
代码是
\documentclass[12pt]{article}
\usepackage{algorithm2e}
\DontPrintSemicolon
\usepackage{algpseudocode}
\usepackage{amsmath}
\pagestyle{empty}
\setlength{\parindent}{0pt}
\begin{document}
\begin{algorithm}[H]
\SetKwInOut{Input}{Input}
\Input{$y'=f(x,y)$}
Assume expansion around $x_0$ with initial conditions $y(x_0)=y_0$
\eIf{$f(x,y)$ analytic at $x_0$}
{

}
{
\eIf{ $f(x,y)$ not linear in $y(x)$}

And so on
}

\end{algorithm}
\end{document}
在 TL 2023 中使用 lualatex 进行编译。
我尝试\;用替换\\，但没有效果。我还尝试添加，\raggedright但没有效果。
我查看并尝试了许多其他与相关问题相关的方法，但无法弄清楚如何纠正这个问题。
我可以使用下面这种新的 MWE 来强制段落之间的垂直间距\vspace。这样可以修复段落间距，但长行上的初始偏移仍然存在

问题是：如何让所有换行的长行都从左对齐开始，而不移动。使用\vspace强制段落间留空是否是正确的解决方案？
答案1
算法的设置方式与常规段落相同。因此，如果你想在语句，你必须以某种方式强制执行。因此，\vspace为此使用某种形式的。下面我使用\medskip。
您在换行的宽语句（段落）中看到的另一个水平错位是由悬挂缩进引起的。您可以通过添加\SetAlgoHangIndent{0pt}到序言中来消除此问题。
\documentclass[12pt]{article}
\usepackage{algorithm2e}

\SetAlgoHangIndent{0pt}

\SetKwInOut{Input}{Input}
