A* Gready algorithm

#2. Discuss the difference of Greedy Best First Search and A* Search, apply the A* search in the given graph, where K and Z are is Initial and Goal states respectively X State Heuristic: h(n) 15 5 K 50 10 V 10 V Y Z W 15 20 X 5 10 25 Y 20 25 K W Z 0 #3(a). C What is an Inference Chain, Draw the inference Chain for the following Rule-Set. Rule 1: If Grade is > B+ and Score is > 70 then Select Rule 2: If Qualification is > 14 and Expr > 3 and Fees is Paid then Score is 70 Rule 3: If Account > 2000 then Fees is Paid #3(b).
