An early AI program that solved problems by closing gaps to a goal.
GPS is like copying a LEGO castle from the box. It spots a missing tower, adds bricks, then hunts the next gap.
In early AI, it used this gap-closing method to solve tasks. It helped inspire Planning, where machines work step by step.
