Hi, the NWERC 2023 will take place on November 24th to 26th in Delft in the Netherlands. We can most likely send two or three teams of three people each. If you have never competed in GCPC, NWERC or similar contests, you can find some additional information below. Since there may be more than 6 to 9 people who are interested, we may have to do a team selection. We will do a qualification contest where everyone competes alone, and the top ranked people in these qualification contests have to form teams and can go to NWERC. The deadline for team selection and registration is around November 3rd. In case of >6 people interested, our qualification contest will take place this weekend on **Saturday, Oct. 28** at 10:30 in Room 407, Building E1.1 on Campus. If you are unable to attend on Saturday, we may be able to let you compete remotely or provide alternative dates. Note that (unlike the competitions themselves) you should bring your own laptop to work on, or contact us if you cannot bring one. Please indicate your preferences on https://dud-poll.inf.tu-dresden.de/nwerc2023/ if you are interested. Also feel free to invite your fellow students to the competition. If you have never competed in a GCPC or NWERC, here is some more information: In the NWERC (http://www.nwerc.eu/) you will work in teams of up to three people on one(!) computer. There are about 10 tasks, and your goal is to solve as many of them as possible. You send in your solution as a program that is evaluated automatically on some secret test data. If the program is both correct and fast enough, you have solved the problem. The contest is 5 hours long. If you want to read some example problems, here are those from 2017: https://open.kattis.com/contests/nwerc17open/problems Task I would be considered an easy task, while for example task H is harder. Allowed languages are C++, Java and Python. A computer will be provided to you. The operating system will be some Linux with common IDEs, editors and compilers installed. If there is a specific software you would like to use, please tell me; I can ask the organizers to install it. We bring a printed team reference document that usually contains code for common algorithms. Bringing further material (e.g. USB-Sticks, Smartphones, pdfs) to the contest or using the internet (except the contest system) are not allowed. We usually find sponsors for the travel and accommodation cost and there is no participation fee. To make the organization easier, we have a Discord Server (https://discord.gg/dmhKxApZCT) and a Telegram group (https://t.me/+Qo3tx2Z82pi_1J3D) If you want to train, I recommend https://cses.fi/book/ (especially for beginners) and https://cp-algorithms.com/ Best, Julian & Simon
