In algorithms, as in life, negativity can be a drag. Consider the problem of finding the shortest path between two points on a graph — a network of nodes connected by links, or edges. Often, these ...

It’s often assumed that Dijkstra’s algorithm, or the A* graph ... as a path finding algorithm, it tries one or more steps in roughly the direction of the destination and selects the shortest ...

If you’ve been making the same commute for a long time, you’ve probably settled on what seems like the best route. But “best” is a slippery concept. Perhaps one day there’s an accident or road closure ...

CATALOG DESCRIPTION: Design and analysis of advanced algorithms: graph algorithms; maximal network flows ... we will design efficient algorithms for a sequence of problems: shortest paths, minimal ...
