Design Principle


The design of Soar is based on the hypothesis
that all deliberate goal -oriented behavior can be
cast as the selection and application of operators
to a state.
A state is a representation of the current
problem-solving situation; an operator
transforms a state (makes changes to the
representation); and a goal is a desired outcome
of the problem-solving activity
