The figure shows a map with several locations on a grid where each tile is 1x1 in size. The locations
are at grid points and are connected by two way edges (roads), where each edge has a cost that is
the same in both directions. Observe that the edge costs are not necessarily proportional to the
coordinate based distance estimates.
The start node is S and the goal node is G, the MoveGen function returns neighbours in
alphabetical order. Use Manhattan distance as the heuristic function.
Tie-breaker: when several nodes have the same best cost, use alphabetical order to break ties.
Emulate A*, WA* and Branch-and-Bound on the given map, then answer the subquestions.
In the map, S is the first node to be refined, determine the next 4 nodes from the 2nd to 5th node
refined by A*. Enter the nodes in the order they are refined.
Enter a comma separated list of node labels.
