摘要: We present a new, efficient and clear method for computing extensions deriving formulas of normal default theory which offers new insight into the nature reasoning seems to be equally successfully applicable open non-normal theories. It is based on semantic tableaux (Smullyan 1968) works theories with finite set defaults are formulated over decidable subset first-order logic. prove that all can produced by constructing tableau one formula built from general laws consequences.
