Here is a collection of links to problems from several European
programming contests. These should be useful for competitors training for
NWERC, NCPC or similar competitions.

Unfortunately, the problems are spread across different online judges.

Warning, broken links galore. I haven't touched this page since 2012.

ACM-ICPC Live Archive - regionals and world finals from 2000 and newer.
TJU online judge - can hold virtual contests here, has many problem sets from regionals.

A nice guide on how to practice.

Subregionals are unfortunately not found on ACM-ICPC Live Archive. NEERC's subregionals are
often pretty good, and some tasks can be found here:

Timus (many Eastern subregionals)
Saratov State University (many Southern subregionals)

Here's a handy link to problems, judge solutions and data sets for a lot of competitions: link

(*) NCPC 2010: G has a (too?) strict time limit, H is missing special judge.
