Search and causal analysis
In Chapter 3 the idea was introduced of representing knowledge as symbolic structures, and knowledge manipulation (i.e.reasoning) as formal symbolic manipulation. We also stressed how each knowledge representation formalism limits the set of allowable symbolic structures and manipulations, thus enforcing a consistent abstraction of the real world and/or achieving useful properties. In this chapter we deal with search, i.e. the general problem of finding a sequence of allowable symbolic manipulations transforming a set of given structures into another target set. Examples of target sets are:
goals to be fulfilled
hypotheses or pre-conditions to be found
hypotheses to be evaluated
