This book provides the latest research on social media use in education and politics. The book is essential for researchers in the fields of e-learning, educational science, ICT, and communication studies. Some chapters are about Moodle or Twitter in classes. Other topics are: Facebook in electoral campaign, efficient cooperation-procedures in web-based training, social media in teacher education, computer mediated social interactions in the educational groups, social media impact on learning. The problems of ACTA, SOPA and PIPA are also discussed.

One of the best known general techniques for developing of the algorithms is the Backtracking method. It seeks to eliminate the generation of all possibilities in order to get the result. The Backtracking method can be applied to those problems for which the solution can be represented as a vector whose elements take values in some finite sets and who meet certain internal conditions. In the Backtracking method, the vector elements are expressed one at a time, assigning a value to a component will be done only after values have been assigned to all its previous components, and no incompatibilities exist between these values. Classical problems solved by this method are: queens’ problem, Cartesian product generation, the generation of combinations, the 0-1 knapsack problem. The book is structured into 7 chapters and provides the solutions to a number of 19 classical problems by using versions of the backtracking algorithm. Most of the paragraphs are followed by a section with solved exercises and problems.

In this book it is presented the architecture of a intelligent system for teaching and checking of the acquisition of certain accounting competences. After presenting several didactic aspects of accounting education and the way in which computer assisted training can be used in learning accounting, we have reviewed the main concepts related to intelligent agents, pedagogic agents and multi-agent systems. The agents are grouped into subsystems. Each subsystem deals with one learning unit. These communicate among themselves in order to achieve the common purpose: the student''s acquisition of accounting competences. Each subsystem is, in its turn, a multi-agent system made up of atomic agents with clearly specified didactic tasks: teaching, testing, assessment etc.

In the context of our research, the following questions arise: Can documentation services be automatized within online electronic resources? Can searches using search engines be automatized? Can online linguistic resources be automatically used? To what extent can distributed work, distributed team research be automatized? or How can we organize agents within a "virtual teacher"? How can we endow a "virtual teacher" with feelings or temperament? How can we extract pragmatic information from different texts? How can we more effectively represent certain notions from a given field? This book will answer such questions by creating a theoretical tool and implementing it as architectures of multi-agent systems.
