Highlights

open to everyone
for teams of up to 3 members
5 hours time
about 10 algorithmic programming challenges to solve

Time & Place

The contest takes place on Saturday, 25 May 2019 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 2019. The system automatically evaluates the solutions submitted for the tasks.

You can test the contest system beforehand at cses.fi. For example, you can try to solve problems from HIIT Open 2016, HIIT Open 2017, and HIIT Open 2018.

The submission system supports the following languages and compilers:

C++: g++ 7.4.0
Haskell: GHC 8.0.2
Java: Java 11.0.2
Python2: Python 2.7.15
Python3: Python 3.6.7
Scala: Scala 2.11.12

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 Aalto Ubuntu Linux computers. You will find there normal text editors and the usual command-line tools, but please do not expect to find any specific IDE. Please make sure you know how to write code with a text editor and terminal.

Registration

There is no registration fee — the event is made possible with support from HIIT and Aalto University.

Registration has been closed now.
