agent architecture; norm compliance; BDI agents; coherenceAbstract:
This paper proposes a reasoning process to allow agents to decide when and how norms should be violated or obeyed. The coherence-based reasoning mechanism proposed in this paper, allows norm aware agents to confront the norm compliance dilemma and build alternatives for such normative decisions.

Coherence; RationalityAbstract:
We propose utility coherence graphs along with coherence maximisation based on Thagard's theory of coherence as an alternative to utility functions to model rational behaviour of agents. We show that the traditional behaviour of utility functions can be emulated using our approach and prove that \emph{the maximum element of a preference ordering is the same as that found by coherence maximisation over a corresponding utility coherence graph}. We argue that utility coherence graphs have marked advantages over utility functions, in that they blend well with the internal representation and reasoning of cognitive agents, and in that they can model the dynamism and uncertainty inherent in the rational behaviour of agents. We illustrate this by modeling the prisoner's dilemma with a utility coherence graph.
