It’s often assumed that Dijkstra’s algorithm, or the A* graph traversal algorithm is ... and preventing awkward situations where for example a truck finds itself wedged into a tunnel or ...

In algorithms, as in life, negativity can be a drag. Consider the problem of finding the shortest path between two points on a graph ... Dijkstra’s greedy strategy. Consider again our delivery driver.

Many different algorithms can solve any given problem, and the question of which is best can be frustratingly ambiguous. For example ... To get a sense of Dijkstra’s algorithm, imagine yourself ...
