| Abstract | DeGroot learning is a model of opinion diffusion and formation in a social network of individuals. We examine the behavior of the DeGroot learning model when external strategic players that aim to bias the final consensus of the social network, are introduced to the model. More precisely, we consider the case of a single decision maker and the case of two competing external players, and a fixed number of possible influence actions on each individual. When studying the influence problems, we focus on the stochastic processes underlying the solution of DeGroot problems. In case of one decision maker, the analysis of the DeGroot model leads to the formation of a Markov Decision Process (MDP) and in the case of two external competing players the model is reduced to a Stochastic Game (SG). Since such models are heavily used in probabilistic model checking we apply tools of the field to solve them. Preliminary experimental results confirm the viability of our approach, which relies on the common mathematical foundations of the DeGroot problems and probabilistic model checking. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
