Abstract: In our research, we try to prove that solving the team formation problem (TFP) on dynamic social networks using evolutionary computations would be advantageous to enhance the accuracy and the time complexity while handling dynamic skill sets for successful completion of tasks. In recent years, different strategies have been proposed to tackle the TFP proficiently. However, because of the dynamic and complex nature that these systems have, solving this problem proven to be NP-hard. This is yet an open problem for further investigation.

The existing approaches in TFP focused on trying to explore the basics of static graphs as the study of their dynamics results. Our research will focus on temporal changes of networks to predict the team members with new possible links.  In order to discover the correct links between individuals to form teams for successful outcomes, we formulated following functions: 1) to examine the active individuals on the considered time-stamp 2) to evaluate the skill similarity among others in the network. 3) for adapted topological knowledge of the networks. The combination of these three major approaches for link prediction on TFP would improve the accuracy of our proposing method. At the same time, modeling a knowledge-based evolutionary framework would reduce the computational complexity. As additional variants of TFP, we are planning to investigate the smart placement for the new individuals, replacement of existing individual and knowledge utilization of team members.
