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.
