Consider 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.
a. Draw the portion of the state space for states 1 to 15.
b. Suppose the goal state is 11. List the order in which nodes will be visited for breadth- first search, depth-limited search with limit 3, and iterative deepening search.
c. Would bidirectional search be appropriate for this problem? If so, describe in detail how it would work.
d. What is the branching factor in each direction of the bidirectional search?
e. Does the answer to (c) suggest a reformulation of the problem that would allow you to solve the problem of getting from state I to a given goal state with almost no search?
