Can you solve algorithmic programming challenges, efficiently and correctly, in practice, as a team, under time pressure?
News
The contest is now over! Many thanks to all participants, and congratulations to the winners!
You can find photos from the event on Storify, or you can check the hashtag #HIITopen on Twitter.
If you missed the contest: there is a virtual online contest with the same problem set. The contest takes 5 hours, and you can start it whenever you want.

Highlights
- open to everyone
- for teams of up to 3 members
- 5 hours time
- about 10 algorithmic programming challenges to solve
- virtual online contest with the same problems available from Sunday, 29 May 2016
Time & Place
The contest takes place on Saturday, 28 May 2016 in the Computer Science building, Konemiehentie 2, Espoo.
Schedule:
- 10:00: doors open
- 11:00: contest starts
- 16:00: contest ends
Please arrive by 10:30.
Rules
The contest is open to everyone, including university students, high-school students, university researchers, and teams from companies.
We will mostly follow the same rules as in the NCPC. In brief:
- each team has 1–3 members
- you can bring any written material with you, but no electronic material
- you can only use the computers, programming environments, and online documentation provided by the organisers
- there is only one computer per team
- printing is possible
- no internet access, no web browsing, no email, no chat, no mobile phones, etc.
Submission system
The CSES contest system will be used in HIIT Open 2016. The system automatically evaluates the solutions submitted for the tasks.
You can test the contest system beforehand at cses.fi. At the moment, there is a practice contest running with some old tasks.
The submission system supports the following languages and compilers:
- C++ compiler:
g++version4.8.4, with the flags-std=c++11 -O2 -Wall - Java compiler: Oracle
javacversion1.8.0_74 - Scala compiler: version
2.11.6 - Python 2 and 3 interpreters
However, please note that there is no guarantee that e.g. Python or Scala implementations can be made efficient enough to solve all tasks — all languages have the same time limits, and they are chosen based on the performance of a reasonably efficient C++ implementation.
Computers
We will use normal Linux computers, which will have the following programming tools installed:
- Editors and IDEs: Eclipse 4.4, gedit 3.4.1, Emacs 23.3.1, Kate 4.8.5, KWrite 4.8.5, vim 7.3
- Compilers: g++ 4.6.4 and 4.8.1, Oracle Java 1.8.0_92, clang 3.0, perl 5.14.2, Python 2.7.3, Python 3.2.3, ruby 1.8.7p352
- Programming tools: ddd 3.3.12, gdb 7.4-2012.04, valgrind 3.7.0
Registration
There is no registration fee — the event is made possible with support from HIIT and Aalto University.
Registration has been closed now, and unfortunately we do cannot accept more participants any more at this point.
