A new model for solution of complex distributed constrained problems

In this paper we describe an original computational model for solving different types of Distributed Constraint Satisfaction Problems (DCSP). The proposed model is called Controller-Agents for Constraints Solving (CACS). This model is intended to be used which is an emerged field from the integration between two paradigms of different nature: Multi-Agent Systems (MAS) and the Constraint Satisfaction Problem paradigm (CSP) where all constraints are treated in central manner as a black-box. This model allows grouping constraints to form a subset that will be treated together as a local problem inside the controller. Using this model allows also handling non-binary constraints easily and directly so that no translating of constraints into binary ones is needed. This paper presents the implementation outlines of a prototype of DCSP solver, its usage methodology and overview of the CACS application for timetabling problems

Vehicle Route Suggestions In Snow Conditions

This disclosure describes techniques for a navigation system to present suggested driving routes for a vehicle that may include roads subject to snow conditions. Under weather conditions that include snow, road conditions such as presence of snow on the road, road steepness, and road width are checked to determine the safety of a road and whether the road is preferable under the weather conditions. Described features inform and guide a user in determining a safe and quick route for a vehicle in potentially unsafe travel conditions

Navigation of blogs related by a tag

Techniques of this disclosure automatically add links to a blog post that enable navigation within a collection of related posts, e.g., posts related by a tag. Blog readers can navigate directly within the linked posts. In a static implementation, the links to posts are automatically updated and stored in a database whenever any post changes. In dynamic implementation, the links to other posts corresponding to a tag are generated when the post is rendered as a web page or upon user selection of a particular tag

Boundary multifractality in the spin quantum Hall symmetry class with interaction

Generalized multifractality characterizes system size dependence of pure scaling local observables at Anderson transitions in all ten symmetry classes of disordered systems. Recently, the concept of generalized multifractality has been extended to boundaries of critical disordered noninteracting systems. Here we study the generalized boundary multifractality in the presence of electron-electron interaction, focusing on the spin quantum Hall symmetry class (class C). Employing the two-loop renormalization group analysis within Finkel'stein nonlinear sigma model we compute the anomalous dimensions of the pure scaling operators located at the boundary of the system. We find that generalized boundary multifractal exponents are twice larger than their bulk counterparts. Exact symmetry relations between generalized boundary multifractal exponents in the case of noninteracting systems are explicitly broken by the interaction.Comment: 14 LaTeX pages, 1 figur
