This is a problem I often face. Sometimes I don't even understand what the problem statements say. It becomes frustrating when I see that many people have solved the problem already while I'm still struggling to understand what to prove or what to find.

I associate this inability of mine with my unfamiliarity with many topics. However, I think I need to learn the art of understanding problems. Therefore, I seek guidance from fellow Brilliants. And, thus comes the real question!

Should we make a thread where people can post links to the problems they find ambiguous so that others can help?

problem. I don't understand what this expression means. However, there are 29 solvers of the problem at this moment. So, I assumed the problem setter used some convention that I don't know of. The problem also doesn't have any link to a relevant wiki. I even tried to google this format to no avail. Is it really a good idea to report a problem which is not wrong (assumption, of course) in any way? – Atomsky Jahid · 1 month, 2 weeks ago

Sometimes I don't think reporting is an option. For example, take a look at thisLog in to reply

"For 0<= y<= 1, find the maximum value of the absolute value of (y^2-xy) for constant x. Now, this maximum value should be a function with respect to x. Find the minimum value of this function for real x" – Pi Han Goh · 1 month, 2 weeks ago

Thanks! I have solved the problem after understanding it. :)Log in to reply

For your problem, you want to minimise a function \(f(x)\) for \(x\in R\), and the function is \(f(x) = \max_{0\leq y \leq 1} |y^2-xy|\). For example, when \(x=0\), \(f(x) = \max_{0\leq y \leq 1} |y^2-xy| = 1\). – Christopher Boo · 1 month, 2 weeks ago
