In this paper we investigate the properties of iterated multiple belief revision. We examine several typical assumptions for iterated revision operations with an ontology where an agent assigns ordinals to beliefs, representing strength or firmness of beliefs. A notion of minimal change is introduced to express the idea that if no evidence to show how a belief set should be reordered after it i...

Finding rna.ximum a posteriori (MAP) assignments, also called Most Probable Explanations, is an important problem on Bayesian belief networks. Shimony has shown that finding MAPS is NPhard. In this paper, we show that approximating MAPS with a constant ratio bound is also NP-hard. In addition. we examine the complexity of two related problems which have been mentioned in the literature. We show...

In this paper, a stability control strategy for underactuated biped robots is proposed based on imbalance degree. The dynamic models of single-leg support of underactuated biped robots are firstly illustrated. Based on the external disturbance force strength of the system, the motion process of an underactuated biped robot is partitioned into three stages according to the imbalance degree. In d...

We derive a Belief-Propagation algorithm for counting large loops in a directed network. We evaluate the distribution of the number of small loops in a directed random network with given degree sequence. We apply the algorithm to a few characteristic directed networks of various network sizes and loop structures and compare the algorithm with exhaustive counting results when possible. The algor...

The concept of reliability is important in epistemology. Most obviously, it is important to reliabilists who build accounts of justification or knowledge that make central appeal to the notion of reliable belief production.1 But even if one does not take the reliabilist line, reliability is still an important concept for epistemological theorizing. In epistemology, most discussion of reliabilit...

Entering the twenty-first century with the development of communities, they are faced with the necessity of moving towards a learning society. University must extend the learning opportunities and improve the quality of them with curriculum design by learning society approach to respond to the necessity. Researchers believe that some conditions for success of this curriculum are required. Prese...

Beyond belief change and meme adoption, both genetics and infection have been spoken of in terms of information transfer. What we examine here, concentrating on the specific case of transfer between sub-networks, are the differences in network dynamics in these cases: the different network dynamics of germs, genes, and memes. Germs and memes, it turns out, exhibit a very different dynamics acro...
