Montgomery Blair Informatics Tournament 2021 Spring Round (Registration live!)
By gabrielwu, history, 4 years ago, In English

Competitors can join our Discord server here.

The Montgomery Blair HS Computer Team is proud to present the fourth iteration of the semi-annual Montgomery Blair Informatics Tournament (mBIT), which will be held online from 10:00 AM — 2:00 PM EDT on Saturday, June 12 (6/12/21). If you are interested in competing, please register at https://mbit.mbhs.edu/. The contest will be hosted on our personal servers at https://mbit.live/. All problems were written by the Montgomery Blair Computer Team, including 12tqian, gabrielwu, galen_colin, smax, meiron03, Blastman, alien_lover, czhang2718, and spiralsim. Special thanks to our testers, Monogon and DenjellBoone!

mBIT is split into two divisions: Standard and Advanced. Teams may choose which division to compete in. Standard division problems are roughly USACO Bronze to Silver difficulty, while Advanced division problems range from USACO Silver to Platinum. Most Standard problems could be found on a Div 3 contest or early on in a Div 2 contest. Advanced problems are more comparable to Div 1 (and more difficult Div 2) problems.

mBIT allows teams of up to 4 competitors! Anybody may compete, regardless of their age or country. There will be Amazon gift cards reserved for the top high school teams in both divisions, in addition to the top overall teams in the Advanced division. To qualify for "high school status," all members of your team must be current high school (or middle school) students.

Prizes (per person):

  • $50, $25, $25 for the first, second, and third HS teams in Advanced

  • $25, $10, $10 for the first, second, and third overall teams in Advanced that are not among the top three HS teams

  • $25, $10 for the first HS team and first MS team in Standard

  • All prize winners will get a Wolfram|Alpha Pro subscription, and the top middle school Standard team will receive AoPS coupons.

Here are the mBIT problems from our most recent contest last November:

All information, including problems from our other two contests, can be found on our website. Registration will remain open up until the day of the contest.

Message me or email mbit.organizers@gmail.com if you have any questions! We hope to see you compete!

mBIT is proudly sponsored by the amazing people at United Therapeutics, Wolfram Research, and AoPS! We are working in partnership with the Competitive Programming Initiative (CPI).

    Perhaps they changed their names to Chinese names to write the problems for this round

Awesome, I can't wait! I saw that the scoring system has changed on the website. Will there still be subtasks?

    Nope, there will not be any subtasks. That being said, there still is partial credit on the system tests (1 point per test case, 20 bonus points if you get all of them right), it's just that you need to pass all pretests to get your program run on the system tests.

What will the compiler flags/compilation command for C++ be? I know pragmas are useless on contests like USACO, but I'm curious whether we can use pragmas on mBIT.

    We compile with O3, and yes, you may use other pragmas.

        O3 is often faster than O2, but you can manually change it with pragmas if you so desire.
