* What is the performance of each approach?
* What is the energy consumption of each approach? (What information do you need to calculate this?)
* Various machines
, such as Aarchie, Bbetty, DDouglas, and a Raspberry Pi 3, have different performance profiles -- so it's not reasonable to compare performance between the machines, but it is reasonable to compare the relative performance of the two algorithms in each context. Do you get similar results?
* What other optimizations can be applied to this problem?
