Online social networks are increasingly important venues for businesses to promote their products and image. However, information propagation in online social networks is significantly more complicated compared to traditional transmission media such as newspaper, radio, and television. In this...

This book was motivated by the notion that some of the underlying difficulty in challenging instances of graph-based problems (e.g., the Traveling Salesman Problem) may be “inherited” from simpler graphs which – in an appropriate sense – could be seen as “ancestors” of the given...

We consider a project scheduling problem where the precedence constraints graph is an out-tree. The processing times can be compressed by using additional resources, which causes cost and simultaneously reduces the processing times of jobs. The objective is to minimize the sum of total lateness...

Predicting linkages among data objects is a fundamental task for applications in various domains. In many contexts link prediction is entirely based on the linkage information itself. Link-structure based link prediction is closely related to a parallel and almost separate stream of research on...

This paper focuses on the application of multi-dimensional Cartesian spaces in the graphical visualization of Gross Domestic Product (GDP) historical trend of any country. The main objective to use multi-dimensional Cartesian spaces is to observe all possible changes of all variables...

The rationale of Econographicology revolves around the efficacy of multi-dimensional (MD) graphs in the storage of meta-database and the visualization of multi-variable data behavior based on the application of Cartesian spaces (or MD Cartesian coordinate system). It is supported by three areas...

Decision makers in the field of national security, counterterrorism and counterinsurgency are faced with an uncertain, adaptive and asymmetrical threat. It should come as no surprise that a great need exists to understand covert organizations, the structure of which becomes known partially only...

Component commonality - the use of the same version of a component across multiple products - is being increasingly considered as a promising way to offer high external variety while retaining low internal variety in operations. However, increasing commonality has both positive and negative cost...
