Technology Arena

20190427 – STEM Games logo – Arena T – bijeli tekst(1)


Various tasks are going to be at different levels of complexity which allows participants a chance to contribute to the team’s success whether they’re facing this type of competition for the first time or if they’re more experienced than that. Teams will win points depending on the success of their solution at individual tasks. The first two days of the competition are focused on solving the algorithm tasks, while the third day is booked for the Main Task. The Main Task’s theme is inspired by the real problems that the Arena’s sponsors are facing every day.


In the Technology Arena, regular computing sciences, mathematics, informatics, and digital sciences students can participate in this type of competition, as well as the other regular students from similar fields.



The progress of digital and informatics technologies has never stopped growing in the last couple of years. We are coming up with new discoveries and knowledge every day that could ease our life with digitalization. This knowledge can also benefit us as a tool for efficient management of everything around us: nature and the environment. This year at the Technology Arena, we’re searching for ways to reduce the impact on natural resources by applying various algorithms and efficient models of machine learning.

I am a fourth-year student at the Faculty of Electrical Engineering and Computing in Zagreb, majoring in Computer Science. My areas of interest range from embedded computers and computer security to quantum computers, nuclear engineering, and various other fields of physics. I am an active member of the student association X.FER. At X.FER, we organize hackathons, competitions, college courses and lectures on various topics in the field of mathematics.

I often compete in different hackathons and CTF competitions. In addition to competing, I organize the course "Cybernetic Security" at FER and am engaged in research on the topic of optimization algorithms on quantum computers.

But life isn't just college, I also like to hike and cook.
