我不断收到可能缺少 \item 的错误

Question

我的 LaTeX 代码有问题。我一直收到错误：

Underfull \vbox (badness 10000) has occurred while \output is active [13]

! LaTeX Error: Something's wrong--perhaps a missing \item.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.
 ...                                              

l.461 \end{algorithmic}

---

LaTeX 代码：

\documentclass{article}
\usepackage{algorithm}
\usepackage{algpseudocode}
\usepackage{pifont}

\begin{document}
\begin{algorithm}
\caption{ glavna\_zanka }%function 
\begin{algorithmic}[1]
\While{ končaj $\not=$ false } 
\State $ rotiraj\_robota()$
 \State obrobje o = $izberi\_raziskovalni\_cilj()$
\If { o $\neq$ null } 
    \State $ premakni\_do\_cilja(o)$
\Else
    \State  končaj = true
\EndIf
\EndWhile
\end{algorithmic}
\end{algorithm}

\begin{algorithm}
\caption{ izberi\_raziskovalni\_cilj() }
\begin{algorithmic}[1]
\end{algorithmic}
\end{algorithm}

\end{document} 

我将非常感激您对这个问题的任何见解。

Answer 1

预期代码主体中有几行代码algorithmic。请比较一个可编译的示例：

\documentclass{article}
\usepackage{algorithm}
\usepackage{algpseudocode}
\usepackage{pifont}

\begin{document}
\begin{algorithm}
\caption{ glavna\_zanka }%function 
\begin{algorithmic}[1]
\While{ končaj $\not=$ false } 
\State $ rotiraj\_robota()$
 \State obrobje o = $izberi\_raziskovalni\_cilj()$
\If { o $\neq$ null } 
    \State $ premakni\_do\_cilja(o)$
\Else
    \State  končaj = true
\EndIf
\EndWhile
\end{algorithmic}
\end{algorithm}



\begin{algorithm}
\caption{ izberi\_raziskovalni\_cilj() }
\begin{algorithmic}[1]
\While
\EndWhile
\end{algorithmic}
\end{algorithm}

\end{document} 

顺便说一句：LaTeX Error: Something's wrong--perhaps a missing \item.很少意味着缺少物品；至少根据我的经验。:-)

Answer 2

看来算法环境需要有一个内容：

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{algorithm}
\usepackage{algpseudocode}
\usepackage{pifont}

\begin{document}
%
\begin{algorithm}
  \caption{ glavna\_zanka }%function
  \begin{algorithmic}[1]
    \While{ končaj $\not=$ false }
    \State $ rotiraj\_robota()$
    \State obrobje o = $izberi\_raziskovalni\_cilj()$
    \If { o $\neq$ null }
    \State $ premakni\_do\_cilja(o)$
    \Else
    \State končaj = true
    \EndIf
    \EndWhile
  \end{algorithmic}
\end{algorithm}

\begin{algorithm}
  \caption{izberi\_raziskovalni\_cilj()}
  \begin{algorithmic}[1]
    \State Lalala…
  \end{algorithmic}
\end{algorithm}

\end{document}
