In the asynchronous distributed system model, consensus is obtained in one communication step if all processes propose the same value. Assuming f < n/3, this is regardless of t...
Abstract— In a peer-to-peer network, nodes are typically required to route packets for each other. This leads to a problem of “free-loaders,” nodes that use the network but r...
Theoretical research has spent some years facing the problem of how to represent and provide semantics to updates of logic programs. This problem is relevant for addressing highly ...
We investigate a generalization of weight-constraint programs with stable semantics, as implemented in the ASP solver smodels. Our programs admit atoms of the form X, F where X is ...
—We use an unconditionally stable numerical scheme to implement a fast version of the geodesic active contour model. The proposed scheme is useful for object segmentation in imag...
