We are pleased to announce that with today’s problem, our summer competition will officially commence. Readers are encouraged to submit their answers to the daily problems and earn points.

Simply click the title of any PotD posted on or after today to access the submission form. For example, you can submit your answers to the first problem here.

For each problem solved correctly, competitors will receive $1$ point. Additionally, solvers are given a small score bonus based on the total number of times a problem is solved as well as the number of people to solve it before them.

The bonus function is monotonically decreasing in both the number of solvers as well as the rank of the competitor. The intent here is that faster solvers and solvers of harder problems will receive a small score bonus.

In order to give everyone a fair shot at solving problems quickly, new problems will be posted every day at $4$ PM EDT. We wouldn’t want to force you to actually wake up in the morning.

Top solvers will receive prizes at the end of the summer. You can view real-time point totals on the Scoreboard to see where you stand.

Points are associated with your forum account, so you will have to register if you have not done so already.

Please note that unless otherwise indicated, the use of computational aids such as calculators or computer software is strictly prohibited. Additionally, guessing will result in ineligibility to receive points for the problem(s) involved.

Feel free to email us if you have any questions.

Happy problem solving!
