The fourth edition of the μ-Games (Mathematics Utrecht) will take place on Friday 14 October, 14.15-17.00, in the Minnaert Mezzanine. This will be a friendly programming contest focused on mathematical thinking. For all problems you must first think mathematically and then write a short program to calculate the answer. The exercise sheet will also include problems aimed at bachelor's students. You can sign up in a team of 3 or 4 students, or individually. In the latter case, we will match you with a few fellow students. During the competition you can program in C#, Java and Python. The event will take place on site, but can also be joined online if you cannot make it on site. If you have questions, you can reach us at: [email protected]. Sign up as a team, or as an individual. Hope to see many of you there!
