I found the problems very cool! However, nobody is talking about it, so I decided to make a blog.
Tasks: https://boi2019.epy.gr/?p=747
Also, can someone post the scoreboard? I used to have a link http://147.102.38.13:8123/Ranking.html but the site died already...
How to do Roadtrip? It feels like doing a weird bfs storing a number of best paths in some form for each node, something like JOI Spring Camp 2017 Wild Boar
Wild Boar is from SC 2018. Anyway, there is no test data? :(((
At BOI, they said they will post the test data about a week after the contest.
Have the test data been released? Charis02
I can't find them online. You can submit here some of the problems http://81.4.170.42:8980/training/#/overview
By the way, Day2 P3 is pretty cute.
Answer for one $$$k$$$ is not fancy :)
Yup, it can be solved e.g. by some straightforward parametric search.
Of course

Do you know test cases were weak? In the first day 2 problems (Dictionary and Fisherman). Some random solutions got 100 scores in a fisherman. And Dictionary some n^2 solutions got 78 scores.

Any updates on tests?
