onsider A* graph search on the graph below. Arcs are labeled with action costs and states are labeled with heuristic values. Assume that ties are broken alphabetically (so a partial plan S->X->A would be expanded before S- >X->B and S->A->Z would be expanded before S->B->A. 1.1 In what order are states expanded by A* graph search? Show the details steps. 1.2 What path does A* graph search return? Show details
