When I asked about what to optimized and also try to give a direction, he give me some hint with vague idea. Neverthless, he seems how to solve a high permutation / combination problem, where I try to through some of the ideas to reduce the dimension or go by store wise. The HM seems interests to solve this in real-time, when I asked about can a physical store be re-arrange in real time, got the response like solve in real time, change the physical store in a weeks time, not able to digest what we are solving, nor have any clue what we are trying to solve.
