The man.

\[~p_n = 1 + \displaystyle\sum_{i = 1}^{2^n}\left\lfloor\left(\frac{n}{\displaystyle\sum_{j = 1}^{i}\left\lfloor\left(cos\frac{(j - 1)! + 1}{j}\pi\right)^2\right\rfloor}\right)^{\frac{1}{n}}\right\rfloor~\]

Problem's point rating system

This is my own point system, other problem setters on LTOL may not apply it.

My problem's point is based on Codeforces problem's rating:

\(100 \leftarrow 800\) CF

\(150 \leftarrow 1000\) CF

\(200 \leftarrow 1200\) CF

\(300 \leftarrow 1400\) CF

\(400 \leftarrow 1800\) CF

\(500 \leftarrow 2600\) CF

After the problems are published, each problem's point will be divided by \(100\), rounded to \(1/5\) and \(\pm\) \(0.4\) based on other contestants' submissions.
