The January Lunchtime is being made unrated due to the various issues that users faced.

With the high traffic that we have been getting recently, we have been facing issues with our infrastructure, and the contest experience has been bad. Keeping this in mind, we are postponing all rated short contests, till a time when we are sure that the contests can be held smoothly, and we’ve had a smooth testing round. In particular, the Starters contest scheduled for 31st January is being postponed till further announcements. Apologies for the inconvenience.

Note: The February Long Challenge will take place as usual.

The contest will be for 3 hours and have 6 problems to solve. It is rated only for the participants of division 3 with their present rating less than 1600. Others can participate unofficially.

Joining me on the problem setting panel are:

Problem Submission: Also, if you have some original and engaging problem ideas, and you’re interested in them being used in CodeChef's contests, you can share them here.
