Transcribed Image Text:

Consider the following implementation of Dijkstra’s algorithm:

vector

vector

typedef pair

}

priority_queue

distances [source] = 0;

q.push (make_pair (0, source));

while (!q. empty()) {

q_entry next = q.top(); q.pop();

if (next.first > distances [next.second])

continue;

for (neighbor n: neighbors [next.second]) {

distance_t new_dist = next.first + n.distance;

if (new_dist < distances [n.node]) {
distances [n.node]
= new_dist;
q.push (make_pair (new_dist, n. node));
}
}
return distances;
Consider further the following graph, which contains edges with negative weights, and more
nodes and edges than shown, repeating the pattern: 99
-98 99
-98
99
-98
What will happen when running Dijkstra's algorithm starting from node A?
