What is the AIO?

The AIO is a 3-hour computer programming competition for students in years 7-12.

Students invent algorithms and write code to solve problems.

Example problem: “Travelling Salesperson” (AIO 2009)

In this scenario, there are three different routes between Perth and Sydney.

Each route has a different number of customers who will buy your encyclopedias.

You are planning a round trip from Perth to Sydney to Perth. What is the greatest number of different customers you can reach along the way?

The next AIO is on 25 August, 2022.
