What does the goal test do?

  • A.Selects which node should be expanded next from the frontier
  • B.Computes the cost of the path from the start to a state
  • C.Generates the successors of the state being examined
  • D.Determines whether a given state satisfies the goal

Answer: D

The goal test is applied to a state and answers yes or no, and it may check a specific configuration or an abstract property such as checkmate. Node selection is the frontier discipline, cost accumulation is the path cost function and successor generation is the transition model. Keeping the five components of a problem distinct is what allows the same algorithm to be applied to problems that look nothing alike.
