Has it changed since last year?

Now I can't run it for last year's tasks (Judge return code: 255)

It works fine for this year's tasks.

World Tour Finals 2018/19 has ended, and we will start the new season soon.

The next two contests will be:

UPD: Due to a fatal trouble (namely, the hardest problem turned out to be known) we had to reschedule it. We are very sorry about this.

And these two will be counted for this season's GP30 race. Like last year, the top 8 (or more, in case we get richer) people of the race ranking will be invited to the onsite finals in the beginning of 2020.

There were several requests to increase the number of contests. Currently our goal is to hold

  • 1 AGC or other all-rated contests per month on average (or 12 per year).

  • 2 ARCs or other <2800-rated contests per month on average (or 24 per year).

(This looks like the maximum number I can handle myself).

We decided to hold a mirror contest of yesterday's finals because there were several requests.

This contest is unrated, but we want to keep it as fair as possible. Please do not participate in case you already know the problems (e.g., participants of Beijing camp), and do not discuss solutions with others during the contest.

This contest is recommended for reds and very ambitious oranges.

Recently we noticed that the number of international participants to ARC-level contests are declining, so we decided to make announcements here.

When a contest is rated for ~2799, regardless of the name of the contest, the problems are prepared in the same way as ARC contests. We try to make the contest interesting even for reds (by the way, you can estimate the difficulty from point values). I think it's rather a div 1.5 contest rather than a div 2 contest (In this particular contest, since there are no divisions, the contest is like div 1.5 + div2 + div3 contest). We always have English editorials for ARCs these days.

Yahoo Programming Contest 2019 will be held on Saturday (time). The writer is DEGwer.
