9. 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. 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 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
