PolyProg welcomes you onto the EPFL campus for a new academic year that will be full of projects, fascinating subjects and student life. To foster long-term success without having the latter fall by the wayside, PolyProg invented a leisure time creator. It is, as is any real system, causal, meaning that an initial investment is required of you in order to reap its benefits.
PolyProg vous souhaite la bienvenue sur le campus de l’EPFL pour une nouvelle année académique riche en projets, matières passionnantes et vie estudiantine. Afin de favoriser votre succès à long terme sans que cette dernière ne reste sur le carreau, PolyProg a inventé une machine à loisirs! Elle est, comme tout système réel, causale, c’est-à-dire qu’un investissement initial vous est réclamé avant que vous n’en puissiez récolter les fruits
The Helvetic Coding Contest 2013 is history! Once again, the best coders from all over Switzerland have met at EPFL in Lausanne to demonstrate their abilities in algorithmic coding.
Please visit the official HC2 website for more information: http://hc2.ch
as a further seminar of our beginner seminar series, Nikolay will explain to you the very basic algorithms when it comes to graphs, Breadth- and Depth-First-Search. You will learn how to implement graphs and how to traverse them using these methods and will solve some basic tasks related to these algorithms. We will in later seminars build up on that knowledge to develop more complex graph algorithms. See you on Thursday, 18:15 in BC 07/08.
The most recent Flash contains a short article about PolyProg! Check it out:
Results from the SWERC contest in Valencia have just arrived. We congratulate the team “Poly Knights” for their excellent 7th place, and team “Evil Poker Faces from Lausanne” for achieving the 21st place (out of 44 teams).
More information and team pictures are online.
This Thursday 22nd, PolyProg will be hosting a short programming contest hosted by facebook (facebook will be at EPFL earlier that day: http://carriere.epfl.ch/). Join us and show off your programming skills!
As usual, we will meet in BC07/BC08 at 18:15.
do you have experience in iOS/Android development? Do you want to expand it while making money?
Junior Enterprise EPFL is an association that helps companies who want to launch small projects find students to do it. Recently, a lot of projects are about mobile app development, and Junior Enterprise is looking for people with knowledge in that domain. Current or prospective projects range from static information display over QR code applications to bluetooth networking! And I hear the pay can be significantly better than what you get as teaching assistant ;) .
Check out their website: http://je-epfl.ch/index.php/pages/view/etudiants

Kudos to all 38 contestants who acted in our thrilling joint EPFL/ETHZ selection contest. At the end of the day, there could be only 6 students to represent the colours of EPFL at the regional finals of the ACM ICPC in Madrid on November 19-20.
The 6 candidates are (ordered by their rank in the contest): Cheng Zhong, Tran Le Hung, Talau Cristian, Johannes Wuthrich, Mihai Moraru and Przemyslaw Pietrzkiewicz. As back-ups qualified Robin Steiger and Octavian Ganea.
The selection committee will announce the final constellation of the 2 EPFL teams (with 3 contestants each) after next week’s training camp at ETHZ.
Last but not least, we’d like to emphasize the exceptional performance of Andrei Giurgiu, who finished as best EPFL student and 2nd overall!

PolyProg launches its series of spring seminars this April 7th.
At this 1st seminar we teach you how to properly brute-force and then tune your code tremendously via fantastic tricks!
There will be some theory, and a lot of practice! By implementing the codes yourselves during the seminar, you get the best of it!
The overall goal of this seminar series is to prepare you for the selection contest (early October) to SWERC 2011 in Madrid, for which we hope to get some fresh blood into the team. We’ll continue then with advanced seminars for proper preparation of SWERC in October and November.
Time: April 7th, 18h15-20h00
Keywords: Brute-force, dynamic programming, search pruning, hands-on
Congratulations to all 83 coders in the 30 teams !!
You can fetch your diploma from ELB241 in case you missed the award ceremony.
Are you tempted to participate in the Helvetic Coding Contest on March 12th, but have no team yet?
Then this seminar is the place to be! Discuss with other interested participants and build your team before the early-registration deadline of February 25th.
Precious tips and tricks await you during this 45’-session in CE103 at 18h15.
PolyProg will pay the 5CHF registration fee for its members (i.e. all students having purchased a membership card for 2010-2011).

… will be held again in BC07/08, Thursday at 18:15.
This time, we will have a look at dynamic programming: When does it make sense to memorize intermediate steps and what is the best way to do this? We will have a look at some algorithms that implement this concept…
Consider the following problem: http://uva.onlinejudge.org/index.php?option=com_onlinejudge&Itemid=8&category=26&page=show_problem&problem=2415
And here, some pictures from last time:
Whether you are preparing for SWERC or not - join online contests, just as Christian suggested in our first seminar!
They are fun, you can practice cooperation in your team or just ameliorate your skills if you compete alone.
As some of you probably already know, there is a moodle page to support the seminars.
Get the link and the enrolment key on the Events -> Seminars page.
[Note: This is an old piece of news, kept for historical purposes only. The Moodle page does not exist any more.]
What exactly is a graph and how can one represent it in a program?
What are good searching strategies and how do you find the shortest path from vertex A to vertex B?
We will have a look at those and other questions in our next seminar, which will take place this Thursday at 18:15 in BC 07/08.
The welcome contest problems are available (and still submittable) at:
Congratulations to the contest winner, Robert! Here, some pictures:
