如何对算法进行编号（将某些算法归为一组）？

Question

我想写几组算法，比如有2个组，每组有2个相关算法。

我不知道在这种情况下如何对每个算法进行编号（如 1.1.1、1.1.2、3.1.1、3.1.2；格式为：

部分数。部分中的组数。组中的算法数。

添加计数器algroup并将计数器设置为自动重置为零。

\documentclass{article}

\usepackage{algorithm}
\usepackage{algorithmicx}
\usepackage{algpseudocode}
\setlength{\intextsep}{2pt}

\newcounter{algroup}[section]
\renewcommand{\thealgroup}{\thesection.\arabic{algroup}}
\counterwithin{algorithm}{algroup}
\renewcommand{\thealgorithm}{\thealgroup.\arabic{algorithm}}

\begin{document}

\section{A}
There is the first group of algorithm
\stepcounter{algroup}
\begin{figure*}[htbp]
  \begin{minipage}[t]{.49\textwidth}
    \begin{algorithm}[H]
      \begin{algorithmic}[1]
        \caption{$A_{1}\left( x_{1} \right)$}
        \State $y_{1} \leftarrow f\left( x_{1} \right)$
        \Return $y_{1}$
      \end{algorithmic}
    \end{algorithm}
  \end{minipage}
  \hfill

        \State $y_{2} \leftarrow f\left( x_{2} \right)$
        \Return $y_{2}$
      \end{algorithmic}
    \end{algorithm}
  \end{minipage}
