答案1

您给出的代码中存在一些问题：

  1. 您需要调用以下包

    \usepackage{algorithm2e} % <============================================
\usepackage{pseudocode} % <=============================================
  2. 我曾经blindtext在文档中添加过一些虚拟文本。
  3. 我添加了一些课堂所需的缺失信息mdpi。

  4. 我纠正了$一些

    Update values of $\alpha$, $\beta$, and $\delta$ using Equation (\ref{H5})--(\ref{H7})\;

使用以下完整的 MWE
