A premature optimization?
Q: Do you have any other insights to offer into how you use maths in your work?
A: For instance, when I brush my teeth I’ve got eight areas to cover, namely Left and right, upper and lower, inside and outside. It’s most efficient to follow a “Hamiltonian path” or “Gray code”:
- left upper outside
- right upper outside
- right upper inside
- left upper inside
- left lower inside
- right lower inside
- right lower outside
- left lower outside
