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
