测试
This is the home page of the competition. You don't need a subtitle here. The competition sub-title will appear above. This is where you introduce the problem. You can upload images using the "Insert Photo" icon on the bar that displays above this textbox when in edit mode.

If you are copy-pasting from another application, like Word or your browser, you may need to clean up the markdown or html for things to display properly.

Here is a handy link to Kaggle's [competition documentation](https://www.kaggle.com/docs/competitions), which includes, among other things, instructions on [submitting predictions](https://www.kaggle.com/docs/competitions#making-a-submission).


## This is a subtitle
To format pages, stick to the following conventions:
- Inline `code` should be encapsulated by back-ticks \``. 
- Block code should have  \``` as the first and last line of the block to produce
```
# code to print hello
print('hello')
```
- Subtitles are prefixed with \##


You can display block equations using LaTeX encapsulated between `\[` and `\]`, and display inline encapsulated between `\(` and `\)` . Note that underscores should be escaped with a `\` for the LaTeX to render properly. For example, this:

\[ \epsilon = \sqrt{\frac{1}{n} \sum\_{i=1}^n (\log(p\_i + 1) - \log(a\_i+1))^2 } \]

is created by this:

`\[\epsilon = \sqrt{\frac{1}{n} \sum\_{i=1}^n (\log(p\_i + 1) - \log(a\_i+1))^2 }\]`
