Q & A

What is the purpose of the International Olympiad in Informatics (IOI)?

The purpose of the IOI is to enhance students' interest in informatics, computer science, and information technology by challenging them to solve computational problems through algorithm design and implementation in a programming language.

When did Indonesia first participate in the International Olympiad in Informatics (IOI)?

Indonesia first participated in the International Olympiad in Informatics (IOI) in 1995.

What achievements has Indonesia had in the International Olympiad in Informatics (IOI)?

Indonesia has won 5 gold medals, 36 silver medals, and 44 bronze medals since its participation in IOI, with notable improvements in recent years, including several silver medals and even a few golds.

How does Indonesia select its participants for the International Olympiad in Informatics (IOI)?

Indonesia selects its IOI participants based on their performance in the OSN Informatics competition, with a multi-stage selection process involving several training camps (Platnas), starting with OSN medalists and progressing through various Platnas levels.

What are the key topics covered in the OSN Informatics syllabus for 2025?

The OSN Informatics syllabus for 2025 includes topics such as programming basics, logic operations and bitwise, arithmetic, combinatorics, search and sorting, problem-solving strategies, data structures, graphs, and basic geometry.

What is the format of the OSN Informatics test for 2025?

The OSN Informatics test will last for 2.5 hours and consist of 30 to 50 questions divided into three sections: computational thinking abstraction, computational problem-solving, and algorithm understanding in C++.

What types of questions will appear in the OSN Informatics test?

The OSN Informatics test will include multiple-choice questions, short-answer questions, and true/false questions. There will be no essay questions.

How is the computational thinking section (Section A) of the OSN Informatics test structured?

In the computational thinking section, participants will be given a problem description, often with illustrations or diagrams, requiring them to apply concepts from informatics to solve the problem. This could involve concepts like graph theory to find solutions.

What will participants encounter in the computational problem-solving section (Section B)?

In Section B, participants will encounter case studies that involve computational problem-solving. They will need to solve these problems without coding, simply by calculating and applying logical reasoning on paper.

What is expected in the algorithm understanding section (Section C) of the OSN Informatics test?

In Section C, participants will be presented with C++ code and will need to demonstrate an understanding of how the code works. They will answer questions based on the code’s logic, without actually running the program.
