latex 算法格式错误 出现问题 - 可能缺少 \item

Question

我正在尝试编写一个算法并收到以下错误

Missing = inserted for \ifnum. \end{algorithmic}


Command \algorithmic already defined. }
Missing = inserted for \ifnum. \end{algorithmic}

Something's wrong--perhaps a missing \item. 
...methodTrace.Method.Owner.DeveloperGold==E}

Something's wrong--perhaps a missing \item. \ENDWHILE

Underfull \vbox (badness 1270) has occurred while \output is active []

Answer 1

您缺少\ENDIF最后一个\IF，并且每个都\IF-\ELSIF需要一个\STATE。此外，if-elsif-elsif-end应该是if-elsif-else-end。
