This came up for me not long ago. A* is a specialization of Dijkstra's that is the canonical "path finding algorithm" for game development. A* is good for finding how to get from a specific point A to a specific point B. But I wanted to know how to get from any point A to a list of point Bs. And so it turned out that the extra work that Dijkstra's does that A* skips is exactly the work you want when doing such a thing. It's also cacheable, which is incredible in the modern era of having basically infinite memory for this sort of thing.
