Latex使用：在latex中添加算法模块

Posted 2020-09-20 Fight boy

在Miktex下有三个latex algorithm包，分别为：algorithm，algorithmic，algorithm2e三个，其中algorithm，algorithmic经常成套使用：

latex中algorithm模板为：

latex文件中顶端加入的package：

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

 

算法块代码：

\\begin{algorithm}[htb]
\\setstretch{1.35} %设置具有指定弹力的橡皮长度（原行宽的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}

实际算法结果图示为：

 

第二种用法：

使用algorithm2e包进行处理

\\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} 

上述代码分别对应两个算法，所获得的算法块分别为：

Latex中的常用算法块如上所述，使用过程中其它技巧可查询之后进行设置。

上述记录仅用来对latex使用过程中的心得体会进行总结。

个人感悟：写latex一定要静下心，要不然很容易出现低级错误。遇到不会的格式或方法，勤用搜索引擎去寻找答案。

 

其实在这里自己是被行距问题卡了很长时间，遇到的问题是因为算法的行距太小：

行距问题的设置网络搜索就可以解决，查阅刘海洋的《latex入门》也可以得到很好解决。
