Points Calculation

To calculate the sum of points $P$ awarded to each solver, the points for challenges across all levels (I, II, III, X) are added up. The points for level X challenges are awarded manually, the points for level I, II, III challenges are calculated dynamically based on the following formula:

P = (\sum_{i = 1}^{L} (\sum_{j = 1}^{N_{i}} \frac{10^{i} * 10}{f (d)}))

$L = 3$ because there are three dynamically calculated levels, $N_{i}$ denotes the number of challenges solved in level $i$ , and the function $f (d)$ is used to calculate the points depending on the number of days passed between the publication of the challenge and the submission of the solution:

f (d) = 1 - \frac{1}{2^{1 - c} * (d + 1)^{c}}

The coefficient $c$ depends on the level $i$ and is defined as follows:

c = {\begin{cases} 1, & if i = 1, \\ 0.25, & if i = 2, \\ 0.1, & if i = 3. \end{cases}

Consequently, the points for higher levels decline slower than for lower levels.
