Problem Solving
It may seem that all agents must solve problems, as indeed they must,
but problem solving in the technical sense is the ability
to consider and attain goals in particular domains using domain-independent
techniques (such as the
weak methods)
as well as domain knowledge. Problem Solving includes
the capability to acquire and reason about knowledge, although the level
to which such capability is supported differs between architectures.
Problem solving, especially human problem solving, has been characterized
as deliberate movement through a
problem space. A problem space
defines the states that are possible for a particular problem
instance and the operators available to transform one state to another.
In this formulation, problem solving is search through the state
space by applying operators until a recognizable goal state is
reached.
