We explain MOEA/D and its slightly modified version with two neighborhood structures. We report some interesting observations on the behavior of MOEA/D with various settings of neighborhood size.

In intentional agents, actions are derived from the mental attitudes and their relationships. In particular, preferences (positive desires) and restrictions (negative desires) are important proactive attitudes which guide agents to intentions and eventually to actions. In this paper, we present a general logical framework to represent and reasoning about gradual notions of desires and intention...

We construct and study a class of translation planes with kernel K ∼= GF (q), order q, and n > 2. These planes generalize the j-planes discovered by Johnson, Pomareda and Wilke in [14]. We show these planes are actually jj · · · j-planes. Hence, most of the results obtained in this article are on jj · · · j-planes. In fact, our study shows that these planes are either nearfield or new. An infin...

In this paper, we define a labelling-based justification status of the arguments in an argumentation framework. Our proposal allows for a more fine-grained notion of a justification status than the traditional extensions-based approaches. In particular, we are able to distinguish different levels at which an argument can be accepted or rejected. Our approach is fully compatible with traditional...

We construct a model of ZF in which there is a measurable cardinal but there is no normal ultrafilter over it.

In this paper we consider the notion of deadlines in the context of dense time. We show that obligations and actions are essential elements for the speciication of deadlines. These notions can be relatively easy combined when a discrete temporal framework is used. However, we show that, once a dense time is introduced , several problems appear. In solving these problems we cannot use the same f...

The aim of this paper is to provide a logical framework which enables reasoning about institutions and their dynamics. In our approach an institution is grounded on the acceptances of its members. We devote special emphasis to the role of legislator. We characterize the legislator as the role whose function is the creation and the modification of legal facts (e.g. permissions, obligations, etc....

We prove the following Main Theorem: ZF + AD + V L(R) =>DC. As a corollary we have that Con(ZF + AD) Con(ZF + AD + DC). Combined with the result of Woodin that Con(ZF + AD) Con(ZF + AD + AC') it follows that DC (as well as AC') is independent relative to ZF + AD. It is finally shown (jointly with H. Woodin) that ZF + AD + DCR, where DCR is DC restricted to reals, implies the consistency of ZF +...
