TopCoder SRM 661 took place very early on Friday after a mostly calm week (problems, results, top 5 on the left, discussion). One of the highlights of the round is the screencast by subscriber where he has also thought aloud and recorded his voice - check it out if you understand Russian!

Codeforces Round 305 started this week's competitions on Tuesday (problems, results, top 5 on the left). Nobody got all problems right despite the promise of an easy contest, and dreamoon got the first place being the only one to solve the two hardest problems correctly - congratulations!

Last week TopCoder Open 2015 Round 2C presented three tricky, if a tiny bit standard, problems (results, top 5 on the left, my screencast, parallel round results). As a result, a fast solution for the easy problem was enough to qualify for the next round, just like in old days :) Of course, ...

IPSC 2015 was the main event of the week (problems, results, top 5 on the left, analysis). The scoreboard looks suprisingly similar to last year: R+T+J on the top with 35 points (great job!), then HoChockiGon. The Polish team is now closer to the first place, with a 3 point gap instead of 6 ...
