Muhammad's Problems

I saw when solving this week's Algebra and Number Theory Level 3 problems that Muhammad A. had two problems featured. Now, I love how Brilliant can give users a more active part by allowing them to submit problems, but putting two from the same user in the same week in the same level doesn't seem right. And don't get me wrong, it's nothing against Muhammad. He seems like a cool guy. I was just wondering why he has two problems in the same week, topic, and level. Also, it showed that he solved his own problem. Why would someone be allowed to solve their own problem if they already know the answer?

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.

It's just another perk of submitting your own problem. Plus, if he has the genius enough to create and submit so many problems to Brilliant, why shouldn't he? It's not like he's excluding anyone else from having their problems shown.

its actually not the same user. I looked. At least, different age and pic. I think users should get problems postponed (still accepted) to hit 1 per week per type per level.

You must be looking at the wrong place, for it is the same Muhammad A. that posed both of those questions. And could you explain to me why a person shouldn't get more than one problem featured each week?

Bob Krueger - 7 years, 11 months ago

There should be no reason why a person shouldn't have more than one problem featured in the same week. If someone's problems are good enough and worthy of being featured, why shouldn't he or she have multiple problems featured? And if two of Muhammad's problems hadn't been featured, we would have faced problem shortages. Some users are complaining about past problems repeating this week.

And @ Matthew, Both the Muhammads are the same user.

Actually, the interesting thing is, I have seen an identical problem that Muhammad posed in NIMO 2011. The link can be found here, Summer Contest Question 11 is exactly the same gcd and lcm problem.

Thanks. Currently, problems are submitted based on the honor system, and I do not check the universe of olympiad problems to see if it has been copied.

Students who continually pass off other's work as their own, will be blacklisted, and might have their participation restricted in other areas. In this case, we have stopped accepting problems from Muhammad.

This as well has the problem named "Muhammad Recurrence". I guess it may have been copied too.[Look for problem number 32 in the first link]. You can also see it here. Question number 32 is exactly the same.

@Aditya Parson – Thanks. I've updated the question to indicate that it is shared.

Calvin Lin Staff - 7 years, 11 months ago

@Calvin Lin – I am sorry to bother you again, but I found yet another copied problem shared by the same person. This problem has been copied too. You can see it here. Question no 12 is exactly the same.

Aditya Parson - 7 years, 11 months ago

We should only submit problems that we made ? what about problems from old Olympiads book ?

Ahmed Taha - 7 years, 11 months ago

@Ahmed Taha – As Bob pointed out, it's fine to submit problems, as long as you credit the source. It could be "I came across this problem during the Training Camp", or even "This problem was used in XX competition, and I really like it for these reasons."

There is no 'penalty' for sharing such problems, especially if they are nice and should be However, we will limit the number of such problems that we use, to give students variety in what they see.

Calvin Lin Staff - 7 years, 11 months ago

@Ahmed Taha – You should credit problems properly, is what Calvin is trying to say.
