| Abstract | We consider the problem of devising optimal timing of on-line campaigns for diffusion of product or information in a population. In particular, we assume that the firm can influence the diffusion process by rolling out campaigns on online forums (we will refer to these as social media campaigns). The problem is to maximize the penetration of the product or given message in the population within the stipulated time. Taking the competitive Bass model as the model of diffusion dynamics, we pose the problem as continuous-time deterministic optimal control problem. We characterize optimal controls, present some numerical results and provide practical insights. We show that the optimal strategy has a simple and elegant structure. We also obtain strategy map which specify the maximum cost at which the firm must stop investing in social media campaigns. In contrast to earlier papers, we also model competition. This is not only close to reality but interestingly it allows to address some problems in completely different contexts. For example, in limiting the spread of misinformation about an entity or an Internet virus, the objective is to maximize nodes with correct information or security patches by immunizing them and/or incentivizing them to spread the information they have to their neighbors. Our work is, thus, applicable to these problems as well. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
