National Olympiad of Informatics (NOI)

The National Olympiad in Informatics (NOI) is organized by the ACM Student Chapter of the University of Colombo School of Computing (UCSC) in collaboration with the Ministry of Education for secondary school students all over the country. In this competition, contestants have to write computer programs to solve a given set of problems, within a limited time. Competing at NOI puts the problem-solving, critical thinking, and logical thinking abilities of students to work.

Only a limited number of students, 16 to be precise will receive the opportunity to participate in the Final Round of this competition.

NOI also serves as the competition which is used to select the Sri Lankan Delegation for the International Olympiad in Informatics (IOI) competition, held annually, in Indonesia this year.

• Competitors will write programs to compute the solutions and submit the solutions for evaluation via the HackerRank platform.
• Each task will be divided into several subtasks, each worth a portion of the total points.
• Time and memory limits will be specified for every task. In general, time and memory limits will be generous (for example, double those required by the expected solution). The memory limit is the overall memory usage including executable code size, stack, heap, etc.
• The solutions must be original. Any case of code plagiarism will disqualify the competitor.
