    aWhat are the key advantages of using Bayes theorem compared to other probability frameworks?
  8. Unit 1
    7 Marks
    bConsider the following graph. The numbers written on edges represent the distance between the nodes. The numbers written on nodes represent the heuristic value. Find the most cost-effective path to reach from start state A to final state J using A* Algorithm.

    bWhat are the main differences between forward chaining and backward chaining in expert systems, and when would you prefer to use each approach?
  13. Unit 1
    7 Marks
    aConsider a state space where the start state is number 1 and the successor function for state n returns two states, numbers $2n$ and $2n+1$. i) Draw the portion of the state space for states 1 to 15. ii) Suppose the goal state is 11. List the order in which nodes will be visited for breadth-first search, depth-first search with limit 3.
  14. Unit 1

    bThe heuristic values for each state are shown below. Given these values, draw a diagram in that illustrates the search tree of explored states, using A* search (the path cost is still a unit cost). Indicate the calculated cost at each node in the tree.
