2021美赛Latex排版美化完整代码2

今天是2月2号，还有三天就打美赛了，我在2021美赛Latex排版美化 完整代码1的基础上又做了一些补充，希望可以帮助到大家。

一、2021美赛新要求

今年的总页数不能超过25页(4)，并且从摘要的下一页开始需要加上页眉，之前的代码是从正文开始算页数的，而且右上角的格式是Page XX而不是 Page 当前页数 of 总页码数（这里感谢某位同学的提醒）。

这是原来的代码部分，需要将\setcounter{page}{1}和\rhead{Page \thepage\ }分别修改并放在对应的位置：

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\clearpage
\pagestyle{fancy}
% Uncomment the next line to generate a Table of Contents
%\tableofcontents
\newpage
\setcounter{page}{1}
\rhead{Page \thepage\ }
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
Begin your paper here


进行以下修改：

\begin{document}\setcounter{page}{1} %将这一行代码放在\begin{document}的最前面


\clearpage
\pagestyle{fancy}
% Uncomment the next line to generate a Table of Contents
\rhead{Page \thepage\ of 20}%将这一行放在\tableofcontents 前面,这样做从目录页就有页眉显示
\tableofcontents %目录
\newpage

修改好效果图如下图：

二、带颜色的表格

除了最基本的三线表格，也许还需要用到比较表格（譬如几个方法的比较）：

需要的宏包以及自定义部分：

\usepackage[table]{xcolor}
\usepackage{colortbl}
\definecolor{mygray}{gray}{.9}
\definecolor{mypink}{rgb}{.99,.91,.95}
\definecolor{mycyan}{cmyk}{.3,0,0,0}


这里貌似需要将\usepackage{xcolor}给注释掉，与上面的宏包有冲突：

\usepackage{graphicx}
%\usepackage{xcolor}
\usepackage{fancyhdr}
\lhead{Team \Team}
\rhead{}
\cfoot{}

编译代码举例（显示效果即为上图Table 2）：

\begin{table}[H]\centering\caption{ four method}\label{y}\begin{tabularx}{0.9\textwidth}{cllll}\toprulemethod & total precision & Pacific Wren & Hermit Thrush&Varied Thrush \\\midruleBayes & 50 & 100 & 16.67& 0 \\\rowcolor{mygray}K-Nearest Neighbors & 29.94 &50 & 16.67 & 16.67 \\Kernel SVM & 36.84 & 12.5 & 16.67 &0 \\\rowcolor{mygray}Logistic Regression & 52.63 & 62.5 & 16.67 &0 \\\bottomrule\end{tabularx}
\end{table}


三、公式

美赛肯定需要写公式，有些美赛论文公式写得真的是很漂亮，看起来老舒服了，人家拿O奖也是有一定道理的。

对应的代码如下：

\subsection{Model Settings}
The transition process is a discrete-time stochastic process.The occurence of immigrants satisfies Markov conditions.Regard to the condition probability $P(N_{n+1}=j|F_n)$,it satisfies the following expression.
\begin{equation}
P(N_{n+1}=j|N_0=i_0,N_1=i_1,\cdots,N_{n-1}=i_{n-1})=P(N_{n+1}=j|N_n=i_n)
\end{equation}
This means that when the status of the immigrations process at time $n$ is known,the status of immigration process after time $n$ has nothing to do with the status before $n$,that is ,no post-validity.We define $p_{i,j}=P(N_{n=1}=j|N_n=i_n)$,then the entire migration of process ${N_n}$ is determined by the $p_{i,j}$and the initial distribution of $N_0$.As we know from assumption,$p_{i,j}$ is only related to country $i,j$,but has nothing to do with $n$,then Markov chain is time-aligned Markov chain.Then write the $p_{i,j}$in matrix from:
\begin{equation}
P=(p_{i,j})
\begin{pmatrix}
p_{1,1}&p_{1,2} & \cdots &p_{1,226} \\
p_{2,1}& p_{2,2} &\cdots & p_{2,226}\\
\vdots &\vdots & \ddots & \vdots\\
p_{226,1}& p_{226,2}& \cdots & p_{226,226}
\end{pmatrix}
\end{equation}
Because the transition probability is positive,and residents will certainly either stay in their own country or move to other countries in the next period, thus,tha matrix has the following properities.(1)$\underset{226}{p_{i,j}}> 0,\quad i,j=1,2,\cdots,226$(2)$\sum p_{i,j}=1,\quad \forall i=1,2,\cdots,226$


这里比较考验大家的latex功底，但是不要害怕，给大家介绍一个非常666的线上latex编辑器，非常方便，还可以实时查看编译是否正确。

四、目录超链接

加入\usepackage[hidelinks]{hyperref}就可以啦~~~~~~~~~

欢迎大家留言私信交流~
