  Scientific literature till date can be thought of as a partially revealed
landscape, where scholars continue to unveil hidden knowledge by exploring
novel research topics. How do scholars explore the scientific landscape , i.e.,
choose research topics to work on? We propose an agent-based model of topic
mobility behavior where scholars migrate across research topics on the space of
science following different strategies, seeking different utilities. We use
this model to study whether strategies widely used in current scientific
community can provide a balance between individual scientific success and the
efficiency and diversity of the whole academic society. Through extensive
simulations, we provide insights into the roles of different strategies, such
as choosing topics according to research potential or the popularity. Our model
provides a conceptual framework and a computational approach to analyze
scholars' behavior and its impact on scientific production. We also discuss how
such an agent-based modeling approach can be integrated with big real-world
scholarly data.
