A Shortcut, "Rule of Thumb," or Guiding Principle Used in Solving

The hill-climbing heuristic involves A) selecting the alternative at each choice point that appears to lead most directly to one's goal. B) trying to find a connection between the current problem and some previous problem. C) attempting various problem solutions sequentially until a successful solution is found. D) starting at the goal state and moving toward the current point in the problem.

Hill climbing is a good problem-solving strategy to use when A) all other heuristics have failed to produce workable solutions. B) a problem has many choice points and the optimal path to the goal is not clearly defined. C) there are similarities between the current problem and previous problems. D) a problem does not have a well-defined goal.
