Document Summary
Problem solving should be understood as the rule-governed transformation of symbol structures. Thinking is simply the transformation of symbol structures according to rules. There are many examples of thinking (daydreaming), but not many of them count as intelligence (thought of as problem solving: examples: chess and travelling salesman. Salesman has to travel to 20 cities as quickly as possible. The search space is possible routes: search spaces are typically represented as trees. Some problems are too complex to search the entire space. Use heuristic search to cut down on time. Gps program is an example of a heuristic search. John searle argues that looking at the manipulations of symbols is the wrong place to look for intelligence. information are sentences in an internal language of thought (mentalese). Information processing works by transforming those sentences in the language of thought. Fodor says that this is what the human brain needs to do. Brains and computers need to solve the same problem.
