乳胶缩进问题

Question

在使用 Latex 语法编写算法时，我遇到了缩进问题，即程序在一个地方开始，在另一个地方结束。部分代码：

\documentclass{article}
\usepackage{amsmath}
\usepackage{algorithm}
\usepackage{algpseudocode}
\makeatletter
\def\BState{\State\hskip-\ALG@thistlm}
\makeatother

\begin{document}
\begin{algorithm}
\caption{Test}\label{euclid}
\begin{algorithmic}[1]

\State $\textit{currentS} \gets \textit{initialS}$
\State $\textit{bestS} \gets \textit{currentS}$
\State $\textit{listTest} \gets \left[ \right]$
\While{$fitness(bestS) < 0$}{
\State $\textit{bestC} \gets \textit{null}$
\For {($\textit{ca} \in \textit{currentS.get})}${
\If{($\neg\textit{listTest.contains(c)})$}{
\EndIf}
\EndFor}
\EndWhile}
\State \Return  $\textit{bestSolution}$
\end{algorithmic}
\end{algorithm}
\end{document} 

Answer 1

你误用了该工具：语法\While是

\While {<condition>}
...
\EndWhile

循环内容周围没有括号。

完整代码（我\State在内部添加了\If）；还请注意\mathit优于\textit。对于空数组，我将其更改\left[\right]为[\,]。

\documentclass{article}
\usepackage{amsmath}
\usepackage{algorithm}
\usepackage{algpseudocode}
\makeatletter
\def\BState{\State\hskip-\ALG@thistlm}
\makeatother

\begin{document}
\begin{algorithm}
\caption{Test}\label{euclid}
\begin{algorithmic}[1]

\State $\mathit{currentS} \gets \mathit{initialS}$
\State $\mathit{bestS} \gets \mathit{currentS}$
\State $\mathit{listTest} \gets [\,]$
\While{$\mathit{fitness}(\mathit{bestS}) < 0$}
  \State $\mathit{bestC} \gets \mathit{null}$
  \For {($\mathit{ca} \in \mathit{currentS.get})}$
    \If{($\neg\mathit{listTest.contains(c)})$}
      \State do something
    \EndIf
  \EndFor
\EndWhile
\State \Return  $\mathit{bestSolution}$
\end{algorithmic}
\end{algorithm}
\end{document}
