Interactive multiobjective optimization methods have provided promising results in the literature but still their implementations are rare. Here we introduce a core structure of interactive methods to enable their convenient implementation. We also demonstrate how this core structure can be...

We consider an iterative preconditioning technique for non-convex large scale optimization. First, we refer to the solution of large scale indefinite linear systems by using a Krylov subspace method, and describe the iterative construction of a preconditioner which does not involve matrices...

The Bega Channel represents a landmark both for the Banat region and for the city of Timisoara, being the proof of progress and of civilization in a century when this area could compete with Western areas from many points of view. Timisoara had had many benefits from the river as a means of...

This contribution proposes a method to make agents in a microscopic simulation of pedestrian traffic walk approximately along a path of estimated minimal remaining travel time to their destination. Usually models of pedestrian dynamics are (implicitly) built on the assumption that pedestrians...

Internet has changed the way companies interact with customers. Customers have become the active part of the communication with business. Virtual communities are the most popular implication of the usage of Internet into business world. The article presents the nature of virtual communities and...

The world shipbuilding industries has started its cycle expansion since 2003, and China has become one of the leading country whose enterprises reached the indicators overtaken the Korean and Japanese ones. The interests in the Far East and Asia-Pacific region concerning our shipbuilding mostly...

The dynamic behaviors of the complex network are crucially affected by its structural properties, which is an essential issue that has attracted much interest. In this paper, the effects of the community structure on the navigability of complex networks are comprehensively investigated. The...
