Physical or simulated agents sharing an environment with humans must evaluate the impact of their own and other agents’ actions in the specific social and cultural context. It is desirable that this social calculus aligns itself with the models developed in sociology and psychology however, it needs to be expressed in an operational, algorithmic form, suitable for implementation.

Abstract— Peer-to-Peer ( P2P ) systems have been the center of attention in recent years due to their advantage . Since each node in such networks can act both as a service provider and as a client , they are subject to different attacks . Therefore it is vital to manage confidence for these vulnerable environments in order to eliminate unsafe peers . This paper investigates the use of genetic ...

Sequential decision problems under uncertainty are commonly studied with stochastic programing. An important modeling choice is the number of stages. More stages allow additional information to be captured, but associated a coarser representation may worsen solution quality. In this paper, we study trade-off, objective advance understanding how affect quality in We show: (i) optimistic bounds f...
