Document Summary

Dealing with uncertainty: focused thinking: goal based, problem solving, decision making, reasoning. Obstacles: no immediate recall of previous solution. Means: operations to change the original state to move us closer to the goal state, cognitive operations, solutions from memory, appropriate allocation of attention, working memory, physical operations. Well defined: completely specified, secret ingredients in chopped are well specified, in the jug problem we have a 3 gallon and a 5-gallon jug. Initial states and goals: also, givens and obstacles, specified means of attaining goals. Ill defined problems: some information is missing. Representation and search: problem solving means moving from initial state to the goal state, representing the problem (initial, searching for the solution (means of transforming) Problem space analysis: problem solving is finding the correct route through the problem space. Information processing tradition: problem space, problem state, problem operators are the moves that you can make to solve the problem itself.
