We propose a method for the modeling and the speculative processing of multi-agent
systems by using constraint hierarchies and hierarchical constraint logic programming. We …

Answer sharing is a key element in multi-agent systems as it allows agents to collaborate
towards achieving a global goal. However exogenous knowledge of the world can influence …

抄録 ルールベースの AI における問題の記述を容易にすることを目的として, 制約論理プログラミング
に制約の優先度を導入した階層的制約論理プログラミング (HCLP) が提案されている. 本研究では …

Speculative Computation is an effective means for solving problems with incomplete
information in an open and distributed environment, such as peer-to-peer environment. It …

Logic programming is a powerful tool for modeling and processing multi-agent systems
(MASs), where problems are collaboratively solved by multiple agents that exchange …

In this thesis we focus upon the problem of derivability of rules from Defeasible Logic.
Derivability of rules, as defined here, comprises the concept of an extension from a …

Cooperation plays an important role in distributed reasoning systems in Ambient
Environment. In such systems, ambient entities with diverse perception and capabilities …
