Technology Arena

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

In the Technology Arena, students will compete in programming. Teams will be given various exercises from different computer engineering branches and their task will be to solve as many exercises as they can in the most efficient way.


Solving communication

In the past several decades, we have seen information technology skyrocket through every boundary we could imagine. This is especially apparent in the case of vast amounts of generated data, which requires development of highly optimized algorithms and design of efficient machine learning models. Our communication channels need to grow and be sustainable as they are the foundation for building new and exciting systems. This battle takes tremendous amounts of knowledge, since the need for communication will grow every single day. We are going to need help if we are to continue broadening our horizons and continue our quest towards knowledge.


Project Assignment

Exercises will be graded depending on the number of solved test examples of a certain exercise. Based on the number of points gained for repeated test examples solving, teams will be able to unlock new exercises. At one point, the main exercise will be unlocked. The main exercise task is to visualize it, design a creative optimal solution and present it to a panel of judges.

Who might compete in the Arena

Full time students studying in the field of Technical Sciences and the related subfields of Digital and Computer Technologies (recommended but not limited to) can compete in the Technology Arena.

Vedran Čaćić

Vedran Čačić

Jury member, PMF Zagreb

Vedran Čačić, a mathematician and logician by expertise and a computer scientist through force of circumstance, works at the Mathematics Department of the Faculty of Science, University of Zagreb as a docent at the Department of Computing. Except for a short period of work on an ethical bank project, he has spent all of his professional life in the comfort of academia, where working on the same problem for 5 years is by no means uncommon. Combining that with a family of four leaves him with very little free time, but what “free time” is is really a matter of semantics, especially for those who love their jobs. He tends to assign his students a lot of work, but they still don’t hate him for it (enough). At times when he gets some free time on his hands, he writes a textbook of some kind or some compiler for an exotic programming language.
