Bitwise 2010 Winners

Bitwise, the Annual Algorithm Intensive Online Coding Contest organised by the Department of Computer Science and Engineering, Indian Institute of Technology, Kharagpur was held on 14th February, 2010. It saw the largest participation, in the terms of both – the number of participants as well as the number of countries.

There were a total of 6000 participants forming 3151 teams from 65 countries. But the bulk of countries came from India, United States, Bangladesh, China and Russian Federation.

This year, Enigma was somewhat easier, at least the long list of winners says so. This puzzle game was inspired by the Enigma machine which was used by the Nazis to encrypt and decrypt messages during the second World War. It consists of images and a hint to crack it. It has 30 levels, and all those who are successful in cracking them all enter the Enigma hall of fame.

The main coding event started at 1200 Hrs (IST) and concluded at 2359 Hrs (IST). In an amazing change over the previous years, this time there wasn’t any single team that dominated the event throughout the competition. Teams climbed up and descended down throughout the 12 hour period.
The first team to crack any problem was urbo, from the University of Latvia. Setting a new record in the history of Bitwise, they cracked the problem in just within 30 minutes of being uploaded. This certainly has been the best time ever made.

urbo was soon followed by teams – Eryx (Warsaw University), Excalibur (TSinghua University), 2/3 ubc^ (University of British Columbia), and Two Headed Monkey (KTH – Royal Institute of Technology & New York University). The teams went up and down and the last two hours saw the team – ajaysomani from google, climb up to second spot.

The final Rankings are as follows:

  1. Eryx, Warsaw University, Poland
  2. ajaysomani, Google, India
  3. urbo, University of Latvia, Latvia
  4. rem and _pperm, Perm State University, Russian Federation
  5. Two-Headed Monkey, KTH – Royal Institute of Technology & New York University, Sweden
  6. NiN, NNSU, Russian Federation
  7. 2/3 ubc^, University of British Columbia, Canada
  8. aryans, IIIT, Hyderabad, India
  9. daemons, Jagiellonian University, Poland
  10. Deadly Coding Squad, ITESM CQ, Mexico

Bitwise 2010 – promising to be bigger than ever..!

Its been just 7 days since the registrations for participation in Bitwise – An Annual Algorithm Intensive Online Programing Contest hosted by Department of Computer Science and Engineering, IIT Kharagpur started. And we have crossed the magic figure of 1000 already. Thanks to all the participants 🙂

What is more interesting is the statistics and the geographical distribution of the registered participants. We have coders from more than 30 countries ! With entries from Cornell, Purdue, Utah, Texas A&M, Florida, Maryland and other top Universities United States has the maximum number of participants outside India. Bangladesh, Poland, Singapore, U.K., and Canada are following US very closely in the number of teams. Rest of the countries have just a couple of teams but we have started receiving many a hits from them lately and are sure that they will catch up the aforementioned very soon.

We even have 4 teams from Iran, and a couple teams from Vietnam, Ukraine, Uganda, Oman and Cuba. And a couple hours back we also received our first team from Kazakhstan. I was so very sure that it is spelled as Kazakhastan and had to look up wikipedia to realize my mistake !

Apart from the Ivy League colleges mentioned above, we also have algorithm enthusiasts from SPb ETU and NNSU (Russian Federation), UWe and Carcow UT (Poland), University of Lugano (Switzerland), Central University of Las Villas (Cuba), BUET (Bangladesh), NUS (Singapore), Bina Nusantara University (Indonesia), PSG and U of Edinburgh (UK), U of Helsinki (Finland), Majan College (Oman), SFU and York University (Canada), DAIICT (Australia), Sharif University of  Technology and Fferdowsi University Mashhad (Iran), MIPT (Ukraine) and the list goes on . . . [Excuse my spellings, I’ve always been poor at Geography 😦 ]

Apart from the Universities and High Schools, a large number of teams from top-notch IT organizations have also participated. Some of them are Microsoft, Cognizant Technology Solutions,  Samsung (SISO), Cisco Systems and Google. Given the huge number of participations in such a short span of time, it seems the 9th edition of Bitwise is going to be big.. really big !

We’re expecting about 5000 teams by the end of next week. And it’s going to be one hell of a job managing all the teams and their submissions on the D-day. Enigma – the precursor of Bitwise has been a huge success with participants trying out their hands at funky puzzles testing their sharpness and ability to relate some really funny pictures with computer terminologies used in day to day life. It has been so successful that there are plans to launch Enigma II on popular demand.

Thanks to our sponsors – Google, Samsung and Synopsis for shelling out money from their pockets so that we could arrange the prizes for our lucky winners.
