This week had quite a few competitions, culminating in the ultimate TCO elimination round where one had to place in top 4. But before we come to that, let's start with TopCoder SRM 695 on Tuesday (problems, results, top 5 on the left, my screencast). The medium problem was from a relatively new ...

As discussed in the previous post, my latest Code Jam problem pointed at approximate algorithms right from the statement: you are given a rooted forest, and consider all valid permutations of its vertices. A permutation of vertices is valid if every non-root vertex comes after its parent.

The main event of the May 16 - May 22 week was ACM ICPC 2016 World Finals in Phuket (problems, results, top 12 on the left). ACM ICPC remains the most prestigious competition for university students for many reasons. First, a very extensive network of regionals and subregionals ensures high and ...

Last week was the lull before the storm, with just one contest among the usual suspects: Codeforces Round 362 (problems, results, top 5 on the left, analysis). TooDifficult has won and confirmed his third place in the overall rating list - in fact, he's now much closer to the top two than the ...

The last week was exclusively on Codeforces. First, Codeforces Round 360 on Wednesday provided top competitors ample time both for solving all problems and for challenging the solutions of others (problems, results, top 5 on the left, analysis). The top 3 stood out because of the challenges, ...

The June 6 - June 12 week started with Codeforces Round 356 on Wednesday evening (problems, results, top 5 on the left, my screencast, analysis). It turned out to be impossible to solve all five problems in time, and thus the winning strategy involved skipping one of the easier problems to spare ...

The May 23 - May 29 week was full with various tournament rounds. TopCoder Open 2016 Round 2B took place on Thursday (problems, results, top 5 on the left). Top 40 have qualified for the Round 3s which was of course the main point, but W4yneb0t wasn't content with just that as he found 100 ...

Let's take a quick break from the World Finals practice session and take a look at last week's events. Codeforces Round 352 on Wednesday was one of the last chances to practice before this week's event (problems, results, top 5 on the left, analysis). Quite fittingly, three out of top five spots ...
