| Chapter 12: Problem Solving Problem solving by analogy: The more similar the problem, the easier the application of the analogy Works better if conscious of the analogy Problem space: (sub)goal states of the problem and solver's knowledge at each step Important to find restrictions in the possible solutions Well-defined problems: have explicit and complete specifications of initial and goal states Ill-defined problems: have vague initial and goal states Lateral thinking puzzles: Have a huge problem space Require checking assumptions about the situation Often lead to hinsight bias Means-end analysis: determine the difference between the current state and the (sub)goal state, then find and apply operator ( = legal operations in the problem) that reduces the difference |
