What is the UKIEPC?

The UKIEPC is the UK & Ireland Subregional Contest for NWERC (the Northwestern Europe European Regional Contest), of the ACM International Collegiate Programming Contest (ICPC). UKIEPC is a practice competition, held annually (starting in 2013) to help universities pick teams to travel to NWERC. The contest does not automatically determine which teams may progress to NWERC, but universities may pitch their teams against other universities around UK and Ireland, to help decide who should be sent. NWERC typically accepts up to 2 teams from each university.

The event itself is organised in a distributed manner. It is physically hosted at several universities around the UK and Ireland. The same problemset is used at all sites. The scores are gathered electronically, and the results can be viewed against other local teams, and teams across the UK and Ireland.

The contest is suitable for programmers of almost all skill levels, from beginner to expert, as the problem set always has both very easy and very difficult problems. There are also separate score tables for the local sites, UK & Ireland level, and even against the entire Nordic contest (while we use their infrastructure). This means you can choose on which level you want to compare yourself.

All the UKIEPC locations belong to the Northwestern European region in the ICPC system. The Northwestern Europe Programming Contest (NWERC) is usually held in the middle of November.

The rules for the UKIEPC are the same as for the ICPC regional contests. In UKIEPC, you are allowed to bring any printed or handwritten material to the contest. No machine readable media or electronic equipment may be brought.

What is the ICPC?

The ACM International Collegiate Programming Contest (ICPC) is a world-wide contest for students and professionals, with local and regional events, and a world final. The contest is about programming skills, problem solving and teamwork. In short terms, teams of up to three students try to solve as many programming problems as possible from a given problem set, using only one computer. See example problems from our past contests or problems on Kattis to get the general idea. You can typically use C, C++, Python or Java to solve the problems, where additional languages are sometimes available.

The ICPC has grown to become very large. Thousands of teams from thousands universities world wide compete in the regional contests which lead up to the World Finals. Less than a hundred team get to go there, but many teams from UK and Ireland have been there the last years.

How do I Participate?

On the web-page for current contest there should be a list of sites hosting the contest. Choose the nearest university that you can get to and then simply register through the online registration system before the deadline.

If you want to participate but don't have a complete team of three please contact your local contest director so they can try to help you connect with other people without teams.

If your university is not on the list, or there is not a location near by, then you can encourage relevant members of staff to become a site host for the contest! Relevant staff vary, and may include student experience officers, or professors/lecturers that teach relevant classes (like algorithms and data structures). It is a great opportunity for inspiring students and showing that programming is fun. If no member of staff is available, then it is possible for PhD students and PostDocs to host a site. The barrier to being a host site is very low, with no requirement to take responsibility other than to be present on contest day in your lab.

Being a UKIEPC Host

Being a host is very simple - all you need is

There is a host slack for staff, postdocs, and phd students that help to host sites.
