我没有细看文档，但似乎「\SetArgSty」可以修改这里的样式
\SetArgSty{<font>} sets the argument typography (by default: emph).\documentclass[fontset=fandol]{ctexart}
\usepackage{graphicx} % Required for inserting images
\usepackage[ruled,vlined,linesnumbered]{algorithm2e}
\usepackage{amsmath,amsfonts}
\begin{document}
\SetArgSty{textup}%
\section{Introduction}
\begin{algorithm}[H]
\SetAlgoLined
\KwData{this text}
\KwResult{how to write algorithm with \LaTeX2e}
\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\;
}
}
\end{algorithm}
\begin{algorithm}[htb]
\SetAlgoLined
\KwResult{每个时间步的参数$\theta$}
\For{第$1,2,\dots,n$个时间步}{
对上一步的态$|\psi(\theta_t) \rangle$作用时间演化算子$e^{-iH\Delta t}$，得参照态$e^{-iH\Delta t}|\psi(\theta_t) \rangle$ \;
初始化$\theta = \theta_t$ \;
求惩罚函数的梯度$\nabla_{\theta}C(\theta)$ \;
\While{$|\nabla_{\theta}C(\theta)| > \text{grad}_{\text{tol}}$ 且 $\text{count} < \text{count}_{\text{max}}$}{
根据梯度$\nabla_{\theta}C(\theta)$，利用ADAM优化器更新参数$\theta$ \;
$\text{count}$加1 \;
求惩罚函数的梯度$\nabla_{\theta}C(\theta)$ \;
}
}
\end{algorithm}
\end{document}嗯...因为我懒得读完全部文档...所以未必是好的实践...
问 在alogorithm2e宏包中如何设置`While`后的关键字为宋体/罗马正体？
