⟩ 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.
