چکیده

Classical planners have traditionally made the closed world assumption facts absent from the planner’s world model are false. Incompleteinformation planners make the open world assumption the truth value of a fact absent from the planner’s model is unknown, and must be sensed. The open world assumption leads to two difficulties: (1) H ow can the planner determine the scope of a universally quantified goal? (2) When is a sensory action redundant, yielding information already known to the planner? This paper describes the fully-implemented XII planner, which solves both problems by representing and reasoning about Zocal closed world information (LCW). We report on experiments utilizing our UNIX softbot (software robot) which demonstrate that LCW can substantially improve the softbot’s performance by eliminating redundant information gathering.

Divine Omniscience and Experience A Reply to Alter

According to one antitheist argument, the necessarily omniscient, necessarily omnipotent, and necessarily omnibenevolent Anselmian God does not exist, because if God is necessarily omnipotent it is impossible for Him to comprehend fully certain concepts, such as fear, frustration and despair, that an omniscient being needs to possess. Torin Alter examines this argument and provides three elabor...
