LaTeX算法环境中的几个错误

大家好，我是 LaTeX 新手，我在算法环境中编写了一个算法，如下所示：

\documentclass{report}
\usepackage{amsmath}
\usepackage{algorithm}
%\usepackage[noend]{algpseudocode}
\usepackage{algpseudocode}

\begin{document}
\makeatletter
\def\BState{\State\hskip-\ALG@thistlm}
\makeatother

\begin{algorithm}
    \caption{Reduct Construction Algorithm}\label{euclid}
    \begin{algorithmic}[1]
        \Procedure{Reduct Construction}{}\newline
        \textbf{Input:} Three matrices based on indiscernibility, discernibility and equal to one relations.\newline
        \textbf{Output:} Reducts (sentences)

\State {{\text{\,\,\,\,\,} \textbf{for} i = 2 to n \text{\,\,\,\,\,}}

\State {{\text{\,\,\,\,\,\,\,\,} \textbf{for} j = 1 to n-1 \text{\,\,\,\,\,\,\,\,}}

\State {\text{\,\,\,\,\,\,\,\,\,\,\,} \textbf{if}$M(i,j) \neq \phi$ \text{\,\,\,\,\,\,\,\,\,\,\,}\textbf{then}

\State {{\text{\,\,\,\,\,} \textbf{for} every non-empty element M(i`,j`) \in B \text{\,\,\,\,\,}}

\State {{\text{\,\,\,\,\,\,\,\,} \textbf{if} $M(i`,j`)\subset M(i,j)$   \text{\,\,\,\,\,\,\,\,}\textbf{then}}

\State {{\text{\,\,\,\,\,\,\,\,\,\,\,\,\,\,} $M(i,j) = M(i`,j`)$ \text{\,\,\,\,\,\,\,\,\,\,\,\,\,\,}}

\State {{\text{\,\,\,\,\,} Divide M(i,j) into two parts\text{\,\,\,\,\,}}

\State {{\text{\,\,\,\,\,} \textbf{Select} an attribute a from M(i,j); \text{\,\,\,\,\,}}

\State {{\text{\,\,\,\,\,} $A = M(i,j)-\{a\}$ \text{\,\,\,\,\,}}

\State {{\text{\,\,\,\,\,} $M(i,j)=\{a\}$ \text{\,\,\,\,\,}}

\State {{\text{\,\,\,\,\,} Simplify every non empty element in B \text{\,\,\,\,\,}}

\State {{\text{\,\,\,\,\,} \textbf{if} {$a \in M(i`,j`)$} \text{\,\,\,\,\,}\textbf{then}

\State {{\text{\,\,\,\,\,\,\,\,\,\,\,} $M(i`,j`)=\{a\}$ \text{\,\,\,\,\,\,\,\,\,\,\,}}

\State {{\text{\,\,\,\,\,} \textbf{Else} \text{\,\,\,\,\,}}
\State {{\text{\,\,\,\,\,} $M(i`,j`) =  M(i`,j`)- A$ \text{\,\,\,\,\,}}

\end{algorithmic}

\end{algorithm}

\end{document}

我使用的软件包是：

\usepackage{amsmath}
\usepackage{algorithm}
\usepackage[noend]{algpseudocode}

有很多错误，虽然可视化是正确的，但当我第一次运行时没有生成 pdf，这很可悲，错误是

Package algorithmicx Error: Some blocks are not closed!!!. \end{algorithmic}
Missing } inserted. \end{algorithmic}
Missing \endcsname inserted. \Procedure
Missing $ inserted. ...{for} every non-empty element M(i`,j`) \in
Extra }, or forgotten $. ... element M(i`,j`) \in B \text{\,\,\,\,\,}}

我尝试纠正它们但失败了，任何帮助纠正这些错误都会很有帮助，谢谢

您滥用了该工具：

\documentclass{article}
\usepackage{amsmath}
\usepackage{algorithm}
\usepackage[noend]{algpseudocode}

\begin{document}

\begin{algorithm}
\caption{Reduct Construction Algorithm}\label{euclid}
\begin{algorithmic}[1]
\Procedure{Reduct Construction}{}\newline
\textbf{Input:} Three matrices based on indiscernibility, discernibility and equal to one relations.\newline
\textbf{Output:} Reducts (sentences)
\For{$i = 2$ to $n$}
  \For{$j = 1$ to $n-1$}
    \If{$M(i,j) \neq \emptyset$}
      \For{every non-empty element $M(i',j') \in B$}
        \If{$M(i',j')\subset M(i,j)$}
           \State{$M(i,j) = M(i',j')$}
        \EndIf
      \EndFor
    \EndIf
    \State{Divide $M(i,j)$ into two parts}
    \State{\textbf{Select} an attribute $a$ from $M(i,j)$;}
    \State{$A = M(i,j)-\{a\}$}
    \State{$M(i,j)=\{a\}$}
    \State{Simplify every non empty element in $B$}
    \If{$a \in M(i',j')$}
      \State{$M(i',j')=\{a\}$}
    \Else
      \State {$M(i',j') =  M(i',j')- A$}
    \EndIf
  \EndFor
\EndFor
\EndProcedure
\end{algorithmic}
\end{algorithm}

\end{document}

我不确定实现是否正是你所想的，但应该很容易调整。

请注意，数学符号应始终位于$符号之间。要为符号添加撇号，请使用撇号'，而不是反引号`
