Latex使用：在latex中添加算法模塊

在Miktex下有三個latex algorithm包，分別為：algorithm，algorithmic，algorithm2e三個，其中algorithm，algorithmic經常成套使用：

latex中algorithm模板為：

latex文件中頂端加入的package：

\usepackage{algorithm}
\usepackage{algorithmic}
\usepackage{setspace}

 

算法塊代碼：

\begin{algorithm}[htb]
\setstretch{1.35} %設置具有指定彈力的橡皮長度（原行寬的1.35倍）
\caption{}
\label{alg:Framwork}
\begin{algorithmic}
\REQUIRE ~~\\
The set of positive samples for current batch, $P_n$;\\
The set of unlabelled samples for current batch, $U_n$;\\
Ensemble of classifiers on former batches, $E_{n-1}$;


\ENSURE ~~\\
Ensemble of classifiers on the current batch, $E_n$;
Extracting the set of reliable negative and/or positive samples $T_n$ from $U_n$ with help of $P_n$;\\
\label{ code:fram:extract }

Training ensemble of classifiers $E$ on $T_n \cup P_n$, with help of data in former batches;\\
\label{code:fram:trainbase}

$E_n=E_{n-1}\cup E$;\\
\label{code:fram:add}

Classifying samples in $U_n-T_n$ by $E_n$;\\
\label{code:fram:classify}

Deleting some weak classifiers in $E_n$ so as to keep the capacity of $E_n$;\\
\label{code:fram:select}

$E_n$;\\
\end{algorithmic}
\end{algorithm}

實際算法結果圖示為：

 

第二種用法：

使用algorithm2e包進行處理

\documentclass{article}
\usepackage{algorithm2e,setspace}

\begin{document}

\begin{algorithm}
\setstretch{1.35}
\SetAlgoLined
\KwData{this text}
\KwResult{how to write algorithm with \LaTeX2e }
initialization\;
\While{not at end of this document}{
read current\;
\eIf{understand}{
go to next section\;
current section becomes this one\;
}{
go back to the beginning of current section\;
}
}
\caption{How to write algorithms}
\end{algorithm}

\bigskip

\begin{algorithm}
\SetAlgoLined
\KwData{this text}
\KwResult{how to write algorithm with \LaTeX2e }
initialization\;
\While{not at end of this document}{
read current\;
\eIf{understand}{
go to next section\;
current section becomes this one\;
}{
go back to the beginning of current section\;
}
}
\caption{How to write algorithms}
\end{algorithm}

\end{document} 

上述代碼分別對應兩個算法，所獲得的算法塊分別為：

Latex中的常用算法塊如上所述，使用過程中其它技巧可查詢之后進行設置。

上述記錄僅用來對latex使用過程中的心得體會進行總結。

個人感悟：寫latex一定要靜下心，要不然很容易出現低級錯誤。遇到不會的格式或方法，勤用搜索引擎去尋找答案。

 

其實在這里自己是被行距問題卡了很長時間，遇到的問題是因為算法的行距太小：

行距問題的設置網絡搜索就可以解決，查閱劉海洋的《latex入門》也可以得到很好解決。
