To calculate the sum of points 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:
because there are three dynamically calculated levels, denotes the number of challenges solved in level , and the function 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 depends on the level and is defined as follows:
Consequently, the points for higher levels decline slower than for lower levels.
