John Dienes’ suggestions using the TSP (Traveling Salesman Problem) and the Held-Karp algorithm are interesting, but they are only unproven theories which ignore the fact that Smith’s Marketplace is operated by Master Marketers using us as experimental animals in a giant maze.
They are using the 2(MM+ DC=GS) X CM with the proven polynomial factor showing that, with Master Marketing, the Distance Covered increases the number of products seen, thus producing Greater Sales, times the number of customers traveling the Maze, of course.
You will notice that the partitions, shelves, interior wine store with its guardian knight, plus the fruit and deli delights are positioned at odd angles to increase the traveling time through the Maze. Eye candy, (look at the clothing and china displays), incites sales.
The solution to the shopping problem is therefore 2(PMP+KB)= EE2 where PMP signifies Practice Makes Perfect plus Knowledge of Bargains equals double Enjoyment and Exercise! One must use repeat visits to learn the Maze locations, resist the eye candy, knowing we are being manipulated, but enjoying the bargains such as the 50 cent ice cream cone, (which is half the price of one at the Golden Arches), and the beautiful view as you eat it at an umbrella table on the canyon-side patio.
