Modelling Agents Roles in the Epistemic Logic L-DINF
No full textIn this paper, we further advance a line of work aimed to formally model via epistemic logic (aspects of) the group dynamics of cooperative agents. In fact, we have previously proposed and here extend a particular logical framework (the Logic of "Inferable"L-DINF), where a group of cooperative agents can jointly perform actions. I.e., at least one agent of the group can perform the action, either with the approval of the group or on behalf of the group. In this paper, we introduce agents' roles within a group. We choose to model roles in terms of the actions that each agent is enabled by its group to perform. We extend the semantics and the proof of strong completeness of our logic, and we show the usefulness of the new extension via a significant example. © 2022 Copyright for this paper by its authors.In this paper, we further advance a line of work aimed to formally model via epistemic logic (aspects of) the group dynamics of cooperative agents.

Temporalizing Epistemic Logic L-DINF
No full textAgents and Multi-Agent Systems (MAS) are a technology that has many fields of application, which extend also to human sciences and where Computational Logic has been widely applied. In this paper, we join together two of our long-lasting lines of work in this field. In particular, we introduce time and time intervals into the epistemic logic L-DINF, that copes with group dynamics in MAS
Preference Management in Epistemic Logic L-DINF
No full textThe Logic of “Inferable” L-DINF has been recently proposed as a declarative framework to formally model via epistemic logic the group dynamics of cooperative agents. In this paper, we extend the framework by introducing the possibility to have costs for execution of physical action. Such costs may require the consumption of multiple resources of various types, to be drawn from agents' budgets. Also, we emphasize that all aspects of Multi-Agent Systems specified in L-DINF can be formalized in a modular way. In particular, concerning the execution of physical actions, dedicated modules allow the specification of a notion of equivalence for actions and a notion of agents' preference, be used to affect action execution
Cognitive Aspects in Epistemic Logic L-DINF
No full textIn this paper, we report about a line of work aimed to formally model via a logical framework -the Logic of "Inferable"L-DINF- (aspects of) the group dynamics of cooperative agents. We outline, in particular, the cognitive aspects built within our logic, that consist in features allowing a designer to model real-world situations encompassing joint intentions and plans with roles, preferences and costs concerning action execution, and involving aspects of a Theory of Mind, i.e., the ability to reason about beliefs of others

Cooperation Among Groups of Agents in the Epistemic Logic L-DINF
No full textThe Logic of “Inferable” L-DINF has been recently proposed as a declarative framework to formally model via epistemic logic (aspects of) the group dynamics of cooperative agents. The framework permits to model groups of cooperative agents that can jointly perform actions. Various aspects of Multi-Agent Systems can be formalized in L-DINF, such as costs of actions, agents’ preferences, and roles of agents within groups. In this paper we extend the framework by introducing the possibility of cooperation among different groups: if a group has not an agent with the right role for performing an action, the group can ask another group in order to have the action performed

An epistemic logic for formalizing group dynamics of agents
No full textIn the multi-agent setting, it is relevant to model group dynamics of agents, and logic has proved a good tool to do so. We propose an epistemic logic, L-DINF-E, that allows one to formalize what are the beliefs formed by a group of agents, where several groups exist and agents can pass from a group to another one. We introduce a new modality which allows an agent to reason about the beliefs of other agents. This allows us to model aspects of the “Theory of Mind”, understood as the set of social-cognitive skills involving the ability to attribute and reason about mental states, desires, beliefs, and knowledge of agents. In this paper, we present the logic L-DINF-E and illustrate how it can be used to solve “false-belief tasks”, i.e., tests in which an agent should understand that some other agent may develop, under some circumstances, false beliefs
