Default Knowledge in Soar
Default Knowledge in Soar
Soar is provided with a set of
productions that provide default
responses to the all the different types of
impasses that may arise
in the course of processing. Subdivisions of this knowledge include:
- Rejecting operators when a conflict occurs in the absence of candidate
problem spaces,
- Establishing operator subgoaling as the default
response to no-change impasses, and,
- Look-ahead search for tie impasses.
Although this knowledge is built using productions, it may considered
part of the architecture as well.
This is because the chunking mechanism
does not learn over the default productions.
Thus, the knowledge represented
by the default knowledge may be considered innate rather than simply
a group of productions that may be combined with others to extend
system capabilities.
