Wouldn't the Dijkstra algorithm visit the negative edge if the
weights were changed as follows; A > B = 1, B > C = 2, A >
D = 4?
I assume that the algorithm goes as follows, Node A is known,
shortest path is to Node B at weight 1, and then it goes to Node C
because of the smallest weight being 3, and then it would visit
Node D via the negative weighted edge.

Consider the following network.
a. (16 pt.)
With the indicated link costs, use Dijkstra’s shortest-path
algorithm to compute the shortest path from “w” to
all network nodes. Show how the algorithm works by computing the
table below. Note: If there exists any tie in each step, choose the
left-most column first.
