Geometry and combinatorics

How is it possible that there are 31 people who solved this week's 300point problem of geometry and combinatorics 133 days ago. I can only assume the problem was posed already a couple of months ago. The ones who solved the problem back then are excluded from this week's competition? How does that work then? Another question is that after solving all problems I keep on getting bumped down the leaderboard not only by people with more lifetime points, but also by people with less lifetime points. How is this possible?

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

  • Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
  • Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
  • Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
  • Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Comments

  • Yes, some of the problems each week have been posed to other users in the past. Users who have seen a problem in a weekly problem set are (almost) never shown that same problem twice. The system avoids showing people repeats although, from time to time, it is necessary.
  • Users who saw the problem back then will see only new problems this week.
  • We are working on clarifying the leaderboard sorting soon. Thanks for pointing out this inconsistency (it looks like you are getting pushed down by more recent problem solvers, which isn't fair.)

is the leader board partially based on lifetime points?In that case,perhaps we need a better criteria for tiebreaking.Who solves first,is again not a good criteria.I may start my problem solving when I get time(maybe friday),and I'll never be able to appear in the leaderboard.number of trials needed to solve a problem seems like a fair criteria.(note:I've even seen my point going up on submitting a wrong answer at the 1st try).
