"In the case of Nissan, we tell the program you cannot schedule back-to-back solutions with sunroofs. [Once] this constraint is in place, [the program will not render] this solution. It is a process of pruning branches from that tree until we get to the [right] solution," Imazarian says.
As Nissan's Simpson puts it, "A human would have to be aware of what is happening at each of the 27 zones every time they place a single vehicle. It's not impossible, but it might take a very long time. So we decided that a machine would be better than the human. I think we were right."
