### Dijkstra's Link State Algorithm (for computing least cost paths)

Consider the 6-node network shown below, with the given link costs.

Using Dijkstra's algorithm, find the least cost path from source node U to all other destinations and answer the following questions

### Question List

1. What is the shortest distance to node z and what node is its predecessor? Write your answer as n,p

2. What is the shortest distance to node x and what node is its predecessor? Write your answer as n,p

3. What is the shortest distance to node w and what node is its predecessor? Write your answer as n,p

### Solution

1. The minimum distance from node u to node z is 8, and node z's predecessor is node w. The full answer was: 8,w

2. The minimum distance from node u to node x is 5, and node x's predecessor is node u. The full answer was: 5,u

3. The minimum distance from node u to node w is 7, and node w's predecessor is node u. The full answer was: 7,u

That's incorrect

That's correct

The answer was: 8,w

The answer was: 5,u

The answer was: 7,u
