The GCPC 2016 is now history and we uploaded all problems from the main contest and the practice session to the contest judge. You can solve the problems there to get further practice. All logins from the GCPC and all our courses work at the judge. The 14 problems are available in new contest as well as in the problem collection.
Here are all files belonging to the GCPC 2016:
We also uploaded three new problems (J&J's, Broken Tetris, and Dolphins) to our collection of course problems. Please feel free to use TUMjudge to prepare for all further rounds of the ACM ICPC!
