我不斷收到可能缺少 \item 的錯誤

Question

我的 LaTeX 程式碼有問題。我不斷收到錯誤：

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}

乳膠代碼：

\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} 

我將不勝感激對這個問題的任何見解。

Answer 1

預期正文中有幾行程式碼algorithmic。請比較一個可編譯的例子：

\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} 

BTW：LaTeX Error: Something's wrong--perhaps a missing \item.很少意味著缺少物品；至少根據我的經驗。 :-)

Answer 2

看來演算法環境需要有一個內容：

\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}
