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:

$L=3$ 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:

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

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