Ralph: Action-Utility Architecture

Description

• The AU architecture uses knowledge of types A, E, and the MEU principle
• Type A knowledge describes the current state, type E knowledge describes the utility of proposed actions
• The MEU principle calculates the best decision D based on the utility of states that are the effect of D and the probability of those states occurring if D is executed in the current state
• This architecture uses standard decision-theoretic reasoning, but there is no explicit planning
