Then what is the problem with treating elevators in the same way that traffic lights are treated in many cities: adjust for the time of day. Using my workplace as the anecdote the elevators get massive usage at 8:00AM as people arrive at work, the majority of calls are from 1st & 2nd floors (you can enter the building on both floors at 8:00, noon and 5:00). After that there is the 9:30-10:30 coffee rush with elevators going up and down. The noon rush, afternoon coffee and evening rush. Those are the peak points of the day with simple scenarios for when people are most commonly going up down so it wouldn't be difficult to implement scenarios where the algorithm changes at a time.
