Multiagent Only Knowing in Dynamic Systems
The idea of “only knowing” a collection of sentences, as proposed by Levesque, has been previously shown to be very useful in characterizing knowledge-based agents: in terms of a specification, a precise and perspicuous account of the beliefs and non-beliefs is obtained in a monotonic setting. Levesque’s logic is based on a first-order modal language with quantifying-in, thus allowing for de re...
متن کاملMulti-Agent Only Knowing
Levesque introduced a notion of “only knowing”, with the goal of capturing certain types of nonmonotonic reasoning. Levesque’s logic dealt with only the case of a single agent. Recently, both Halpern and Lakemeyer independently attempted to extend Levesque’s logic to the multi-agent case. Although there are a number of similarities in their approaches, there are some significant differences. In...
متن کاملLogical Spaces in Multi-agent Only Knowing Systems
We present a weak multi-agent system of Only knowing and an analysis of the logical spaces that can be defined in it. The logic complements the approach to generalizing Levesque‘s All I Know system made by Halpern and Lakemeyer. A novel feature of our approach is that the logic is defined entirely at the object level with no reference to meta-concepts in the definition of the axiom system. We s...
متن کاملOnly Knowing in the Situation
Actions depend crucially on what an agent knows and does not know. For example, an action may have a precondition that requires knowing the referent of a term, which is generally referred to as knowing who or knowing what. Alternatively, executing a sense action may be the result of realizing that the referent of a term is not known yet. The latter requires an agent to reason about all it knows...
متن کاملProbabilistic reasoning in dynamic multiagent systems
Probabilistic reasoning with multiply sectioned Bayesian networks (MSBNs) has been successfully applied in static domains under the cooperative multiagent paradigm. Probabilistic reasoning in dynamic domains under the same paradigm involves several issues. This paper proposes an approach to address these issues. Intuitively, observation on current state plays a more important role in the reason...
