The authors interpret the task of credit assignment as the ability of a system to identify and distinguish strategy components to associate with such components in different regions of the domain of confrontation, good and poor outcomes of a sequence of actions prescribed by the strategy to improve the boundaries of these regions in minimizing the errors of misclassification of strategy actions to estimate the overall quality of a strategy being the sum of the qualities of strategy components weighted by the probabilities of employing them and to provide information for a meta-strategy that shifts the domain of confrontation to those regions in which the strategy studied is most proficient and, thereby, raises the effective quality of the strategy. The paper describes the program QO-4 -- the fourth module of a large system, the Quasi-Optimizer -- which can accomplish the above tasks within certain limitations.
