Where Search Should Fit in an AI System
We can identify two extremes in the use of search:
- Traditional programming (no search):
inflexible.
- Doing everything with search: too slow.
The ideal is to:
- Replace search by knowledge when possible.
- Heuristic function is one kind of knowledge.
- Experts vs. novices: Experts ``just do the right thing'';
novices search.
- Fall back on search when knowledge is
insufficient.
