> ... Recognizing problem complexity as a first step...

Well, I don't think it's easy or even generally possible to recognize a problem complexity. Imagine you ask for a solution for a simple expressed statement like find an n > 2 where z^n = x^n + y^n. The answer you will receive will be based on a trained model with this well known problem but if it's not in the model it could be impossible to measure its complexity.
