Thanks!
OK, so would this tell me the actual path, or just how many blocks that path is? I understand that we are building a matrix with minimum distance, Im just not completely clear on how we're doing it.
I have a weighted, undirected graph. I have a Minimum Spanning Tree for that graph. One edge (u,v), with weight w, is added to the graph.
How can I update the minimum spanning tree in O(V) time?

Thanks, Sfel, but I really have never coded a breadth first search before. Could be a little more clear on exactly how i'd go about keeping track of the minimum path, or WHY it always gets the...
Could I use breadth-first search, implemented with an adjacency list, which is O(E+V)?
I'm not arguing that you dont look ahead, obviously blindly choosing a path wouldn't result in an optimal solution, or O(n) time. I think we need to look at the problem, and the dangerous...
adak - Wouldn't evaluating each move to 2 levels bring the algorithm to O(n^2)?
I think there's some insight into this problem that none of us are getting.
Thanks for your help. There is definitely a solution, as I've found almost the exact same problem in textbooks (dating back to 1998) when googling for an answer.
That's why I think it's not just...
Im not extremely familiar with shortest-path algorithms, which can I use to solve this in O(XY)?
Hey, long time reader, first time poster.
I'm working on a dynamic algorithm, and I've hit a roadblock in my thought process. Here's what I'm trying to do:
I'm given a X x Y rectangular grid in...
