Hi Everyone!↵
↵
This year Australia is hosting the Asia-Pacific Informatics Olympiad (APIO). Since the official contest window is about to end for contestants, the APIO 2017 Open contest will begin soon! Everyone is invited to participate, and would be good practice for IOI-eligible students.↵
↵
The contest has a similar format to the IOI, having 3 tasks over 5 hours and will be hosted on the CMS Contest Management System at [contest.apio17.org](contest.apio17.org). The contest will be run in two separate windows, each having the same set of problems as the official contest.↵
↵
1. Window 1 begins [UTC+0 15.00, Monday, May 15](https://www.timeanddate.com/worldclock/fixedtime.html?msg=APIO+Open+Contest%3A+Window+1&iso=20170515T15&p1=1440&ah=5)↵
2. Window 2 begins [UTC+0 11.00, Tuesday, May 16](https://www.timeanddate.com/worldclock/fixedtime.html?msg=APIO+Open+Contest%3A+Window+2&iso=20170516T11&p1=1440&ah=5)↵
↵
Please note that these times have been pushed back by 24 hours from what was originally advertised on our website.↵
↵
The supported languages are C11, C++11 and Pascal only. Task statements will be available in English, Chinese (Simplified), Chinese (Traditional), Hebrew, Bahasa Indonesia, Japanese, Korean, Mongolian, Persian, Russian, Thai, Turkish and Vietnamese, with many thanks to the leaders of the respective delegations for providing task translations. Detailed rules for the contest can be found on the contest website [http://apio17.org/competition/rules/](http://apio17.org/competition/rules/). Unfortunately, clarifications will not be available during the open contests.↵
↵
If you would like to participate, please register using the [Registration Form](https://goo.gl/forms/gwvawBBa4P0eB8AH3). Registration for each contest will close two hours prior to the start of the contest.↵
**Update:** Once registrations close, you will be emailed a username and password to use to log in to the contest site. Please check your email before the contest begins!↵
↵
To ensure that each contest is fair, we kindly ask all participants to refrain from discussing the problems until the end of the second open contest window. **Update:** As a result, please **do not** participate if you have already competed in the official contest. If you did compete and have already registered, please don't login and compete on the contest system. If you are still competing in the open contest, please only participate and register for one of the two contest windows. Thank you for your co-operation.↵
↵
Looking forward to your participation!↵
