Ironically this appears to have been written by AI. I stopped reading when I noticed.

Huh, this seems like a cool optimization problem that I gotta dig in later. As sweeping was mentioned, there's an argument to be made that we could/should optimize for: - longest possible strides, you can pick up speed and minimize used time - allowing overlapping strides on "intersections", as intersections have more traffic and thus should have more grime and wear. - back-and-forth sweeping along a stride. Like with grass or mopping a floor, if there's any "evidence" left of the sweeping, it'll be more aesthetically more pleasing. - finally minimizing extra turning, as turning is slow

If someone has any extra suggestions on what restrictions/optimization targets there should be and the rationale for that, I'd be more than happy to receive them!
