Their approach enables a robot to "think ahead" by evaluating thousands of possible solutions in parallel and then refining the best ones to meet the constraints of the robot and its environment.

Link state protocols use characteristics of the route such as speed and cost as well as current congestion to determine the best path, which is typically computed by the Dijkstra algorithm.

Contraction hierarchies are a simple approach for fast routing in road networks. Our algorithm calculates exact shortest paths and handles road networks of whole continents. During a preprocessing ...
