| Interesting video.

| I've often wondered what the most optimal elevator algorithm is.
| Imagine a scenario where a single person calls an elevator to go
| down, and just as they get in, a group of five people on the
| floor above also call the elevator to go down. We all know that
| the elevator would go straight down and then come back up for the
| people who called the elevator too late.
|
| The elevator could actually save more time by letting the person
| on the lower floor board, going one floor up, and letting the
| group board before going back down. The algorithm could factor in
| the number of people waiting on each floor, the time taken to
| travel between floors, and how many people are already on the
| elevator into account to optimise its route.
|
| With multiple elevator shafts there's even more things to think
| about. Could one shaft serve a lower set of floors while another
| shaft serves a higher set of floors to minimise 'wasted' time
| travelling up and down? Could the algorithm take into account the
| time of day and the ingress/egress of people from the building?
