However, proved that they have low efficiencies in finding a near-optimal solution in large-scale networks. Heuristic Function is a function that estimates the cost of getting from one place to another (from the current state to the goal state.) A lower priority request can execute CS before a higher priority request if the higher priority request is delayed. Then on a search for a path towards A, those saved G scores represent the real distances to A. Jump to navigation Jump to search. Informatica.
