Scoping out the right problems is a highly non-trivial skill in itself. For example, a significant component of a PhD is learning to do this with regards to research projects (that is part of what it means to be an independent researcher). Typically, the only way to learn this is by calibrating one's experience with one's ability, and the scope of problems will evolve with the increase in both. It really helps to have a mentor to provide guidance along that path, and to help set/refine goals and to calibrate expectations and provide feedback. The reason I'm explaining all this is that it is very difficult to generically suggest "problems" without knowing your background/interests/orientation. (eg: Coming up with good student projects is an art unto itself; something that professors are expected to learn along the way) So maybe provide some more information about yourself? Appreciate the initiative; good luck! Maybe we should develop more of a culture of sharing "problems" openly (formulated constructively) so that others with a suitable background might take a crack at them! :-)
