Document Summary
Complex and high-level skill that fills up gaps in the evidence (bartlett, 1958). Process of searching through a problem space (newell & simon, 1972). Well defined have beginning and end rule or guidelines (they"re ill defined) Ill defined: problem solving tehniques, generate and test. Useful if there is a limited number of possibilities. Can"t keep track of possibilities tested: means ends analysis. Goals state: condition at the end of problem. Intermediate states: the various conditions that exist along pathways between the initial and the goal state. Reduce the difference between initial state and goal state. Any sequence of moves beginning at the initial state and ending at the final goal state. Involves generating a goal and then sub-goals constitutes a solution path: working backwards. Involves creating sub-goals and reducing differences between the current state and the goal state (like means-ends analysis) But sub-goals are created working backwards from the goal state. I didn"t do great on the last test.
