Document Summary
Well-defined problems- solving the tower of hanoi puzzle, constructing a proof in algebra. Ill-defined problems-writing a paper on democracy figuring out how to throw a surprise birthday party for your friend. What differentiates well-defined from ill-defined problems: whether or not all three key elements of a problem space (= initial state, goal state, & operators) can be specified. Metaphor: search through a space toward a goal. Key elements in a problem space -initial state, goal state, operators (tools or actions that lead you from one state to another), optional: constraints (e. g. , certain states or operators are not allowed) Key words: problem space; initial states; goal states; operators; well-defined vs. ill- defined problems. Algorithm = a procedure that, if followed correctly, guarantees that one reaches the goal state: example: following a well-specified cooking recipe, May not be the most efficient approach, trying to identify the pin number you can"t remember (e. g. , 0000, 0001, 0002, etc. )
