When searching for a route between two cities on a large road map, a common heuristic used is the A* search algorithm. This algorithm combines the benefits of both Dijkstra's algorithm and greedy best-first search by using a heuristic function to estimate the cost of reaching the destination from any given node. A* selects the node that minimizes the sum of the cost-so-far and the estimated cost to the goal, guiding the search towards the most promising paths while also guaranteeing optimality under certain conditions.
