Pre-EC on this weekend

2017-04-02

As in previous years, there will be a "demo round" before the EC, called the Pre-EC. This gives you the opportunity to test our submission interface and the evaluation process, and lets us check our infrastructure. You can also use the Pre-EC's problems to practice handling the file formats you may have to deal with during the EC. We think it's highly advisable to try the Pre-EC.

The Pre-EC is 10 hours long to accommodate various timezones and schedules, but it doesn't typically require more than a couple of hours to solve the tasks.
