Arthur Sun

BIG Scholar 2024 | IOI Medalist

Arthur’s journey into computer science began in middle school, where he first discovered a passion for solving problems with code. He began competing in informatics a few years ago, then his interest expanded to areas such as AI and cybersecurity, where he also competes. At Cambridge, he looks forward to applying the problem-solving skills and creative mindset he has developed through his competition experience.
We caught up before he started university (interview edited for length and clarity):
GTF: What have you been up to since graduating high school?

AS: For the past year, I’ve been hanging around in Australia, where I'm from. I look forward to starting university at Cambridge, though there’s a lot of unknowns. I can’t point to a specific thing I’m excited for because I haven’t experienced uni yet, but the idea of starting is really exciting.

GTF: Are there any specific topics or classes you look forward to studying?

AS: I’m doing computer science at Cambridge, and I’m really interested in areas like AI and cybersecurity. I’ve been doing those this past year. During high school, I was more focused on the Informatics Olympiad, which is mostly algorithms. But in the past year, I’ve been doing online competitions like CTFs [Capture the Flag], and I’ve really enjoyed that.

GTF: How did you get interested in informatics and start participating in the Olympiads?

AS: I started around Year 8 or Year 9, so about four years ago. What got me into informatics was solving problems with code. Like Google Maps—you convert roads into graphs and run an algorithm to find the shortest path. That’s what initially got me into it, and I’ve been doing it ever since.

GTF: How do the algorithmic competitions compare to the AI or cybersecurity competitions you’ve been doing?

AS: They’re different, but in a lot of ways, they’re similar. For all kinds of problems, you have to come up with some innovative approach. Whether it’s informatics, AI, or cybersecurity, you need to find an edge—some insight that other competitors don’t have. That’s what I like most, thinking creatively.

GTF: Did you learn computer science on your own or through school?

AS: It was mostly through personal research. I started getting into it around Year 7 or Year 9, but it wasn’t really through school—more just my own interest. I worked on things like coding generative models and finding my own data to train them. I enjoyed doing that kind of stuff.

GTF: How has your experience in competitions shaped you?

My experience has been good, especially in informatics. I’ve been doing it for about three or four years and went to the IOI in 2022. It’s been a really positive experience. I’ve only been doing AI and cybersecurity for about a year, but informatics has definitely shaped how I approach problems—building intuition and thinking creatively, which I think will be useful at university.

GTF: Do you have any advice for people starting out in informatics competitions like IOI?

AS: If you’re competing in something like the IOI, you’ve probably been doing informatics for a few years. It’s a big competition, so you need to be prepared. But stress too much about the competition itself. You should learn for your own sake, not just for the competition. Even if it’s stressful, the knowledge and experience will stay with you, so don’t worry too much about the results.

GTF: What mindset will you take from informatics to university?

AS: I think the main thing is learning to build intuition when solving problems. A lot of what you learn in computer science becomes outdated pretty quickly, but the way you approach problems sticks with you. That’s the biggest takeaway for me—learning to think creatively and come up with new solutions.

GTF: Do you use creativity outside of computer science?

AS: Yeah, I think creativity shows up in a lot of places. Like, I played tennis for a bit, and you kind of build your approach to a match based on your opponent. It’s vague, but you need creativity to figure out a strategy. It’s similar to how you approach problem-solving in computer science.
