Question
Transcribed Image Text:c) Consider the following search problem, represented as a graph. Each node is labelled
by a capital letter and the value of a heuristic function is shown in maroon. Each edge
is labelled by the cost to traverse that edge. The start state is 'S' and the only goal
state is 'G'. Perform the A* search to find the shortest path from node S to node G by
answering the following two questions:
ii.
Is the heuristics specified in the problem (shown below) admissible? Justify your
answer. If the heuristics is admissible, proceed to answer part (ii). If the heuristics
is not admissible, correct it with a sensible value of your choice and proceed to
answer part (ii).
Perform the A* search to find the shortest path from the start state (S) to the goal
state (G).
