Summer finally has come! So I want to tell about cool summer Internet Problem Solving Contest or IPSC. It's very interesting internet-contest. You can participate as a part of the team, or individually; there is also secondary school division on same problemset, but with separate results.
Usual problem are algorithmic output-only, but there are also some tricky challenging. As example, in previous contest there was problem where you had to take care about your dog — right answers decreased your penalty on 20 minutes, incorrect answer would cause death of your animal :-)
Today, June 1 at 08:00 UTC starts practice tour. It's recommended to everyone to participate in it, there are also interesting tricky (previous year) problems.
Contest starts at 10:00 UTC 2 June. GL & HF!
