CHAPTER 7 DEFINITIONS PROBLEM REPRESENTATIO N the first step in solving a problem; it involves interpreting or defining the problem TRIAL AND ERROR works best with limited choices INFORMATION RETRIEVAL look to methods used in past-works if quick solution needed ALGORITHM a step by step method that guarantees a correct solution eg. math rules 4 x 4=16 HEURISTICS a rule of thumb that helps in simplifying and solving problems, although they do not guarantee correct solution (may get you to within reach) include: hill climbing, subgoals, means-end analysis, working backwards HILL CLIMBING a heuristic problem solving strategy in which each step moves closer to goal (step-by-step evaluation) eg. multiple choice question-first eliminate wrong answers

Unformatted text preview: SUB GOALS intermediate, more manageable parts used in one heuristic strategy to make it easier to reach final goals MEANS-END ANALYSIS heuristic strategy to reduce discrepancy between current situation and desired goal at a number of intermediate points eg. walk a batter to avoid bit hit WORKING BACKWARDS begin at goal and work backward. Use if there is more information about end than given eg. have $100 spend amount and subtract what is left, spend more subtract SET the tendency to perceive and to approach problem in certain ways- CAN BE HELPFUL OR OBSTACLE FUNCTIONAL FIXEDNESS tendency to perceive only a limited number of uses for an object, thus interfering with problem solving...
