Ralph: Decision-Theoretic Architecture

Description

• The DT architecture uses knowledge of types A, B, and C, and the MEU principle
• Type A knowledge describes the current state, type B knowledge describes the effects of proposed actions, and type C knowledge evaluates the utility of new states
• 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
• Type B knowledge can be chained to look ahead several steps
• This architecture uses standard decision-theoretic reasoning to determine the ideal action
• This knowledge can be compiled for use by other architectures
