Hi everyone, The time has come for the yearly programming competition "IDI Open". It will take place Saturday April 14, 2018. The contest proper runs from 11:00 to 16:00, but to be sure that you are ready at 11, you must show up at 10:00. The local site for the contest will be the Nygaard building (https://www.openstreetmap.org/relation/6237769#map=19/56.17173/10.19002), more specifically in room 395. Soda, snacks and pizza (or similar) will be provided. Please tell me if you are competing so I can order a sufficient amount of pizzas / buy enough soda and snacks by filling out: https://goo.gl/forms/Kk9LrT9nTEe9KdUa2 Please sign up no later than Friday April 13, 15:00! Teams consist of 1-3 people. You need to sign up in the Google form above as well as at https://idiopen.idi.ntnu.no/open18/team/register/. If you have participated previously you should be able to reuse your old account. Note that the deadline for registering on the official IDI Open site is Thursday April 12, 18:00. Please bring your own laptop. Last year, every team was able to bring their own laptop. If you for some reason do not have a laptop available, please contact me and I will try to figure something out. For those of you new to programming competitions, the format is as follows. You will work in groups of size 3 or less. You are given a set of exercises (typically around 10), which you have 5 hours to solve. Your team is provided one computer to solve the exercises. The solution is a program written in C, C++, Python2, or Java. You upload this program to the judging system, which will then tell you if the solution is correct or not. You win by solving the most exercises. The exercises are algorithmic in nature so you will have to devise an algorithm that is fast enough. The competition follows the same rules as the ICPC competitions.

While the contest is a test of skills, you do not have to be super good to compete. If you just want to have some fun and some free pizza, why not show up and see what it is all about? Hope to see you for the competition! -Freksen PS. I am aware that this invitation came quite late and I am sorry for that. I hope that some of you can attend the competition despite this late reminder.
