This question already has an answer here:
Like let’s say you find the shortest path, but you want to find an alternate path as well. In order to do that, you have to ignore each edge in the shortest path one at a time, and then find the shortest path without using that respective edge. At that point you have a set of alternate paths, of which you want to select the one that is the shortest yet also different enough.
But I don’t know how to find the alternate paths while skipping edges. Could anyone please clear this up
