The ICPC South Pacific Regional Finals were held this past weekend in Sydney, Australia. The top 12 teams from the region (Australia, New Zealand, Fiji) competed for an invitation to World Finals.

Two World Finals spots were awarded:

The full scoreboard can be found here. I will put up the contest into the Gym in the next few days once I relax a little bit from all of the organization last week. =)

Congratulations to the teams and good luck at World Finals!

UPD: I have added the contest to the Gym. I hope everyone enjoys the contest!

UPD 2: The editorial for the contest can be found here.

Is there any analysis somewhere?

Alternatively, hints for H?

    The analysis was given in an oral presentation at the Regional Finals. I am at a conference right now, but after I'm done here, I plan on writing up/publishing a thorough write up. But to help out in the short term, here are some hints:

    Helpful steps (without spoiling much)
    More helpful steps (spoiling quite a bit, but not everything)

    Hope this helps!

Are there plans to release the judge input/output files publicly?

      That's great — thanks a lot!

      Also, is similar data from previous years available anywhere? Our university's teams have been wanting to practice on regional sets from South Pacific, but it has always been impossible for us to find the judge data for testing teams' solutions (at least since 2011).

        Short answer: Unfortunately, other than 2015 (here) and 2016, no data has been made officially available other than the ability to submit to ICPC Live Archive. I could possibly dig up the data for the 4 questions that I wrote for the 2014 set if needed, though.

        Somewhat longer answer: I only arrived down here in 2014 and the old Chief Judge in the region believed that everything on the judging end should be kept secret to not reveal any trade secrets, so he never released anything. I'm the exact opposite and believe transparency is the only correct way to do judging, so I release everything (hence why there is data available for the last two years), and I hope for this practice to continue indefinitely.

          That's awesome! I appreciate the change in policy, as I very much agree with your philosophy of transparency in judging, and I am looking forward to being able to practice on future South Pacific regional sets. :)
