Luger © 2002 Addison Wesley 8. The use of meta-level knowledge to effect more sophisticated control of problem solving strategies. Although this is a very difficult problem, addressed in relatively few current systems, it is emerging as an essential area of research. 7. The use of large amounts of domain-specific knowledge in solving problems. This is the basis of expert systems. 6. Answers that are neither exact nor optimal, but are in some sense “sufficient.” This is a result of the essential reliance on heuristic problem-solving methods in situations where optimal or exact results are either too expensive or not possible. 5. An attempt to deal with issues of semantic meaning as well as syntactic form. 4. Reasoning about the significant qualitative features of a situation. 3. A concern with problem solving using inexact, missing, or poorly defined information and the use of representational formalisms that enable the programmer to compensate for these problems. 2. A focus on problems that do not respond to algorithmic solutions. This underlies the reliance on heuristic search as an AI problem-solving technique. 1. The use of computers to do reasoning, pattern recognition, learning, or some other form of inference.
