Three heuristics for problem solving were presented in the text. Choose two heuristics and explain how they are different
What will be an ideal response?
Answer: With the random search (or generate and test) heuristic, the problem solver picks moves and evaluates the outcome on a trial and error basis. With the hill climbing heuristic, she looks one step ahead and picks the move that most closely resembles the goal state. With means-ends analysis, the problem is broken down into subproblems until a solution to the subproblem is found.
