In the Fall of 2023 we are hosting a problem solving session every Friday from 5pm to 7:30pm (more information about this below). This is open to everyone interested in competitive programming, regardless of how experienced you are. There is also no commitment, so feel free to show up at any of the sessions. We will have free food and snacks during each session.
If you want to know more information about competitive programming check our about page. We also have a resources page with lots of links to materials of all levels for you to practice and learn more. Finally, if you are thinking about competing in the International Collegiate Programming Contests, check our contests page.
We have a Discord channel, to join please contact Pedro Paredes (pparedes_at_cs.princeton.edu).
We have regular sessions every Friday from 5pm to 7:30pm in Friend Center Room 006. You will need a laptop and optionally pen and paper to work on problems. Also, you don’t have to be there for the full two and a half hours, if you can only show up for an hour, please feel free to do so!
Each week will start with a 2 hour problem solving session followed by a 30 minute discussion of the problem solutions.
Each session is divided into two groups: the division I group; and the division II group. You are free to choose whatever group you want and you can switch at any point.
The division II group is intended for those with little or no competitive programming experience. The problems will often have associated readings for you to learn new concepts.
The division I is intended for those with experience in competitive programming. Each session will contain problems of varying difficulties to target different levels of experience.
Note that most problems have appeared before in other competitions from around the world.
Our sessions are going to be hosted on a platform called codeforces. You will need an account in order to solve problems here. We also have a group you can join by going to the following link: https://codeforces.com/group/hNnRWqFua0/ (you should click on join on the right in order to access the problems).
