\section{Assumptions and Notations}
\subsection{Assumptions and Explanations}
Considering those practical problems always contain many complex factors, first of all, we need to make reasonable assumptions to simplify the model, and each hypothesis is closely followed by its corresponding explanation:
\begin{itemize}
	\setlength{\parsep}{0ex} %段落间距
	\setlength{\topsep}{2ex} %列表到上下文的垂直距离
	\setlength{\itemsep}{1ex} %条目间距
	\item Assumption 1: The data provided in this problem is valid and reliable.
	\item Explanations:
	\item Assumption 2: There's no maximum/minimum xx limit for..
	\item Explanations:
	\item Assumption 3: The xx factors can be ignored./The xx does not influence xx.
	\item Explanations:
	\item Assumption 4: We do not ...
	\item Explanations:
	\item Assumption 5: The xx is the xx.
	\item Explanations:
	\item Assumption 6: xx and xx do not affect each other.
	\item Explanations:
\end{itemize}



\subsection{Notations}
In this work, we use the nomenclature in Table 1 in the model construction. Other none-frequent-used symbols will be introduced once they are used.

\section{Data Description}
\subsection{Data Collection}



\subsection{Date Pre-processing}
The data we use includes the data files given as \textbf{mingzi}.

Since we are only allowed to use this data set provided by timudeofficial, we need to pre-process the data for the datasets before solving the problem.

Notice that there are...

To facilitate the follow-up process, and to ensure the reliability and reasonableness of the data, we take (the average of the prices of the two trading days before and after each trading day with missing gold price as the gold price of that day.The trading days eith missing gold price and their corrected gold prices )are shown in the table below:

%一种数字化写法：$\mathcal{P}$





























\section{Sensitivity Analysis}
In Task 1, we introduce the attenuation coefficient  and assign it a value of 0.5 in order to measure the effect of indirect influence in the influence network, and now we do a sensitivity test on the attenuation coefficient $\mathcal{P}$.
%图片
From the figure we can find that there is no large change in the influence when $\mathcal{P}$ is taken at [0.1,0,8]. Therefore, our model is insensitive to $\mathcal{P}$ in most cases.
