Aussie teens score three medals at informatics Olympiad


Four Australian programming whizzes stepped up to the challenge at this year’s International Olympiad in Informatics (IOI) and scooped up three medals. In a wild finish to the two-day competition and under a live scoreboard, Jerry Mao, Angus Ritossa and Albert Smith all achieved high silvers, narrowly missing the gold medal cut-off. They competed against 335 students from 87 countries who attended the 30th annual IOI in Tsukuba, Japan, this week.

Jerry Mao, a year 12 student from Caulfield Grammar in Melbourne’s Wheelers Hill, added the silver to his collection. He has represented Australia outstandingly in the last four IOIs and medalled every year. The IOI contest is held over two days. On each day students attempt to program solutions to three problems over four and a half hours.

This marks the eighth consecutive year the Australian team has received three or more medals.  The Australian Mathematics Trust (AMT) supports the team.

‘Congratulations to the entire team on another very strong result at the IOI,’ said Australian Mathematics Trust CEO, Nathan Ford.  ‘Informatics is such a critical subject for young Australians to engage with and our result this year is a testament to the hard work of our team.’

The AMT offers opportunities to enrich primary and secondary students’ problem solving in mathematics and algorithmics. The AMT has been sending an Australian team to the IOI since 1992.  The team of four is selected from an annual program of competitions, training schools and mentoring with final selection taking place in April.

The AMT’s IOI program receives grant funding from the Australian Government through the National Innovation and Science Agenda.  It is also supported by the Trust’s corporate sponsor, Optiver.

Australian student solves hardest problem in history of competition

The Australian team is bringing home three silver and two bronze medals, plus an honourable mention, from the 2017 International Mathematical Olympiad (IMO) in Rio de Janeiro, Brazil.

This year’s competition contained the hardest problem in the history of the IMO. Only seven students scored any points on the question, and only two, including Australia’s Linus Cooper, completely solved the problem. Australia has the distinction of scoring more points than any other country on this question with Hadyn Tang also achieving a partial score on the problem.

The Australian Mathematics Trust’s (AMT) CEO, Nathan Ford, said: ‘We had a great overall team result and it is a significant achievement for Australia to score more points than any other country on the hardest IMO problem in history. It shows how well our competitors are trained in solving complex problems. It’s a testament to Linus’ training, focus and perseverance that he solved it.’

The Australian team finished 34th out of 111 countries in the 58th International Mathematical Olympiad. The South Korean team were the outright winners, with each competitor earning a gold medal.

Six hundred and fifteen students participated in the IMO from the across the globe. The competition was held over 18 and 19 July with competitors having to solve three problems over four and a half hours each day.

The Australian team spent a year in exams and intensive training to make the Olympiad selection. They succeeded amongst more than 25,000 students participating in extension programs and qualifying exams. From that initial cohort, some thirty students attended two training schools before the final selection of the team.

The Australian results were:

2017 International Mathematical Olympiad
Rio de Janeiro, Brazil
12 to 23 July

Student School State Result
James Bang Baulkham Hills High School NSW Bronze medal
Matthew Cheah Penleigh and Essendon Grammar School VIC Silver medal

Melbourne student is first girl ever picked for Australian Informatics Olympiad team

Belinda Shi, a year 12 student from Methodist Ladies’ College in Melbourne, will be the first Australian girl to compete at the International Olympiad in Informatics.

“I’m excited to be the first female on Australia’s International Olympiad in Informatics team,” she says.

Keen to counter the misconception that ‘girls can’t code’, Belinda decided to establish a coding club at school. Her goal is to introduce other girls at her school to informatics, programming and robotics. “I want to encourage girls to keep an open mind and give programming and technology a go, because learning to code is not only fun and rewarding but it’s a skill that’s useful in so many fields,” she says.

According to research commissioned by the Australian Computer Society, women hold only 28 per cent of Australian ICT jobs compared to 43 per cent of professional industry jobs. Encouraging girls to learn coding at school is a critical part of the challenge to increase the number of women in ICT careers.

Members of the Australian Mathematical and Informatics Olympiad teams are pictured above: (from left) Wilson Zhao, Ilia Kucherov, Johnny Lim, Jerry Mao, Richard Gong, Kevin Xian, Declan McDonnell and Belinda Shi; and inserts (from left) are Seyoon Ragavan and Michelle Chen.

Members of the International Mathematical Olympiad (IMO) team, Michelle Chen and Seyoon Ragavan, are part of a cohort of 10 international special guests to be invited to train at the United States Math Olympiad Summer Program, which is running from 7 June to 2 July at Carnegie Mellon University in Pittsburgh, Pennsylvania. This is a high honour for Michelle and Seyoon as the US is the reigning champion in the IMO. Australia has been invited due to our very strong performances at recent IMOs.

Twenty-seven of Australia’s brightest student biologists, chemists, computer programmers, physicists, mathematicians and Earth scientists have been selected to represent Australia at the UNESCO-sanctioned International Science and Mathematical Olympiads in July and August. The students have succeeded from an initial pool of more than 150,000 high school students who sat open qualifying exams, including the Australian Science Olympiad Exams and the Australian Mathematics Competition. The Australian Mathematics Trust runs the Mathematical and Informatics Olympiad programs.

The Olympians will compete against 2000 of the world’s smartest kids at competitions in Vietnam (Biology), Georgia (Chemistry), Japan (Earth Science), Russia (Informatics), Hong Kong (Mathematics) and Switzerland (Physics). They will receive their Australian team blazers at a team announcement ceremony at Parliament House, Canberra, on Monday 20 June. Media personality and maths whiz Adam Spencer will attend the ceremony together with one of Australia’s leading mathematics professors, The University of Sydney’s Dr Jacqui Ramagge, parents, teachers, academics, Olympiad alumni and officials.

“At a time when we are seeing a declining proportion of students choosing to study advanced maths and science subjects at high school, it is vital to have these national Olympiad programs to nurture and celebrate our science and maths talent,” says Adam Spencer.

Students inspired to win a place at next year’s International Science Olympiads can register for the Australian Science Olympiad Exams by 20 July at Students interested in next year’s International Mathematical Olympiad still have time to enter the Australian Mathematics Competition through their schools at

The Olympiad programs are supported by the Australian Government Department of Education and Training through the Mathematics and Science Participation Program. BHP Billiton Sustainable Communities and the Australian National University are supporters of the Australian Science Olympiad Competition. Optiver is a sponsor of the Mathematical and Informatics Olympiad programs.

Thursday 7 August 2014

Media personality and The University of Sydney’s Mathematics and Science Ambassador, Adam Spencer, visited his daughters’ local primary school to wish the students good luck in the 37th annual Australian Mathematics Competition (AMC) sponsored by the Commonwealth Bank.

AMC Day with Adam Spencer

Adam believes passionately in the need to promote the importance of mathematics and demonstrates his commitment by providing voluntary maths tutoring at the school. With his encouragement, the school entered the AMC for the first time. Adam’s daughters and their schoolmates joined the nearly 30,000 students new to competing in the AMC.

Students of all levels of ability, from all types of schools in vastly different locations around the country, sat a 75-minute secondary paper or a 60-minute primary paper which contained some quirky questions with an emphasis on fun and problem solving.

Adjunct Professor Mike Clapper, Executive Director of the not-for-profit Australian Mathematics Trust, which administers the competition, said,

‘We were delighted to welcome a number of Australian schools who will be participating in this historic competition for the first time, especially primary schools, as encouraging the study of maths at an early age is vital. It is also good to see entry numbers increase in the Northern Territory and the ACT’.

‘The competition is designed to be accessible to all students but it also identifies the most talented, who can then go on to a series of Trust enrichment programs that nurture their special ability and may lead to success, such as for the two Australian students who topped this year’s International Mathematical and Informatics Olympiads, achieving perfect scores, gold medals and tying for first ranking globally’, he added.
