Part 1: Single Source Shortest Paths with Dijkstra's (5 pts) 8 7 Iteration 1 9 9 2 Nodes a b c d e f g h z 4 11 3 1 6 10 f h 6 2 Distance 0 Previous NIL Iteration 2 For convenience, we assume the Source Node is Node a. Use and track the record table using Dijkstra's to find out the shortest paths from Node a to all others and the corresponding paths taken. You may use the following empty table or those in the appendix as a template. At the Initialization stage, the table would look like: Nodes a b c d e f g h z Distance INF INF INF INF INF INF INF INF INF Previous NIL NIL NIL NIL NIL NIL NIL NIL NIL After Iteration #0 where you put Node a into the incorporated subgraph and relax Node a's neighbors, the table would look like: Nodes a b c d e f g h z Distance 0 4 8 INF INF INF INF INF INF Previous NIL a a NIL NIL NIL NIL NIL NIL Iteration Final (aka Iteration 8) Nodes a b c d e f g h z Distanc 0 Previous NIL Your job is to figure out the record tables after you finish Iteration 1, Iteration 2, and the final Iteration where you complete the Spanning Tree subgraph of the single source shortest paths from Node a. You may simply fill up the templates on the next page.
