International Olympiad in Informatics
The International computer science Olympiad ( English International Olympiad in Informatics, IOI ) has made a registered per year computer science competition for students. The first IOI was held in 1989 in Bulgaria.
Each country may send up to four participants. In 2004 took part in about 80 countries. In the countries most national preliminary rounds will be organized to determine the four participants.
Progression of the competition
At each of the two days of competition, the participants usually get three tasks of algorithmic nature. To solve are five hours. During this time, participants must alone and without help solve the problems and implement. For this purpose, a computer with the necessary tools and programming environments are available; Communication with other participants, consulting books or other aids are not permitted. To achieve the objects is mostly with a computer program to create, either in C, C or Pascal, and this is to be transmitted within five hours from the start of the competition to the jury.
After the competition, the programs will be checked with hitherto secret test data, usually 10 to 20, consist of several test cases. Points obtained for each test case correctly solved; there are also predefined time and memory limits to be observed. In some cases, programs are to create, interact with the jury program, such as simple games. In a more recent nature of the assignment, the test data during the competition are already known, participants only need longer give the correct answers to the input data. This is, for example, the decryption of encoded texts.
In the IOI 2010 in Waterloo for the first time the current scores of each participant were published on the Internet. In addition, 2010 saw a video broadcast of the competition on the internet.
The points of all tasks on both days will be added. At the award ceremony the best of the basis of their total points lined up participants will receive medals. It received about 50 % of all participants a medal. The gold, silver and bronze medals will be awarded in the ratio 1:2:3, so receives about one-twelfth of all the participants a gold medal.

Participation
Who wants to participate in the IOI, must qualify in their own country first. The mode is different depending on the country, often applied a two-level system. The tasks of the first round to be solved at home, the best solutions come in the second round. There must be resolved as in the IOI for five hours several tasks. The top four this round will be the World Cup, the IOI approved. The German IOI team, for example, from the finalists of the competition researches federal competition computer science and youth selected. In several rounds of competition, which shall include participation in the Baltic computer science Olympiad ( BOI), the top four will be selected. In preparation for the IOI, the selected members of the German team also take part in the Central European computer science Olympiad ( CEOI ).
Austrian computer science Olympiad
Austria took part in the IOI in 1992. The most successful Austrian participants were previously Wolfgang Thaller, each with two gold and silver medals in the years 1996-1999 and Thomas Würth Inger with the world's third place in 2003.
The preliminary round proceeds in two stages. The top ten, who qualify in a preliminary round to be completed at home to fight in the final round of the four starting positions in the IOI. The competition is organized by the Austrian Computer Society and maintained by Karl Fuchs, Helmut Achleitner, Johann Fellner and Gerald Futschek.
