Worked decisions, with the assumptions left in
Reproducible examples showing where the data came from, which rules were applied, what alternatives were considered and why the recommendation passed its checks.
Illustrative examples, not customer data. Real recommendations are generated from your own inputs.
“One van, five drop-offs, back to the depot. The stops sit on a city grid — A(2,4), B(5,1), C(6,5), D(1,7), E(8,3), depot at (0,0) — and driving distance is the grid distance in km. Which order is shortest?”

The answer
The shortest round possible — all 120 stop orders were measured, and none beats 32 km.
32 kmRound distance
- Drive Depot → A → D → C → E → B → Depot
- Legs: 6 + 4 + 7 + 4 + 5 + 6 = 32 km
- Longest leg: D → C at 7 km
Driving the stops in list order (A, B, C, D, E): 46 km — 14 km longer.
Add a sixth stop at (4,8) and the best round grows only 2 km, to 34 km.
