a) Regression planning
Explanation:
Backward state-space search will find the solution from goal to the action, so it is called as Regression planning.

b) Sub-goal independence
Explanation:
Sub-goal independence approach is to pretend that a pure divide and conquer algorithm will work for admissible heuristics.

27. What is state space?
a) The whole problem
b) Your Definition to a problem
c) Problem you design
d) Representing your problem with variable and parameter
e) A space where you know the solution

d) Representing your problem with variable and parameter
Explanation:
Because state space is mostly concerned with a problem, when you try to solve a problem, we have to design a mathematical structure to the problem, which can only be through variables and parameters. for example, you have given a 4-gallon jug and another 3-gallon jug. Neither has measuring marker on it. You have to fill the jugs with water. How can you get exactly 2 gallons of water in to 4 gallons.Here the state space can defined as set of ordered pairs integers(x,y),such that x=0,1,2,3 or 4 and y=0,1,2 or 3;X represents the number of gallons in 4 gallons jug and y represents quantity of water in the 3 gallons jug.

29. A search algorithm takes _________ as an input and returns ________ as an output.
a) Input, output
b) Problem, solution
c) Solution, problem

30. A problem in a search space Is defined by:
a) Initial state
b) Goal test
c) Intermediate states
d) All of the above

a) Initial state & b) Goal test
Explanation:
A problem has four components initial state, goal test, set of actions, path cost.

31. The set of actions for a problem in a state space is formulated by a ___________.
a) Intermediate states
b) Initial state
c) Successor function, which takes current action and returns next immediate state
d) None of the mentioned

c) Successor function, which takes current action and returns next immediate state
Explanation:
The most common formulation for actions uses a successor function. Given a particular state x, SUCCESSOR-FN(x) returns a set of (action, successor) ordered pairs, where each action is one of the legal actions in state x and each successor is a state that can be reached from x by applying the action.

32. A solution to a problem is a path from the initial state to a goal state. Solution quality is measured by the path cost function, and an optimal solution has the highest path cost among all solutions. State whether true or false.

b) False

a) True
Explanation:
A solution to a problem is a path from the initial state to a goal state. Solution quality is measured by the path cost function, and an optimal solution has the lowest path cost among all solutions.
