如何在投影仪的算法中缩进/对齐线？

Question

预期输出为

我的输出是

在我的输出中，Brancing位于正确位置。前 3 个项目应从 向右移动，Brancing并且Bounding应向右移动，以便与 对齐Brancing。第二 3 个项目应从 的新位置向右移动Bounding。
如果与预期匹配，则混淆。

为了将项目符号与“分支”对齐，您可以手动插入项目符号，而无需使用 itemize 环境：

\documentclass{beamer}
\usetheme{Madrid}
\usepackage{algpseudocode}
\usefonttheme[onlymath]{serif}

\begin{document}

\begin{frame}[fragile]
    \begin{block}{BnB algorithm for QWSRM problem}
        \begin{algorithmic}
            \State Branching:
            \State\quad\usebeamertemplate{itemize item} Set $\mathcal{Q}$...
            \State\quad\usebeamertemplate{itemize item} Split $\mathcal{Q}$...
            \State Bounding:
            \State\quad\usebeamertemplate{itemize item} Update $u_{k+1}$
      \end{algorithmic}
  \end{block}
\end{frame}

\end{document}
