Outline of Final Research Achievements

It is confirmed that networks observed in various fields have a characteristic called complex networks. Some of complex networks are built by a large number of agents with high judgment ability, and a dynamic network formation game model based on the game theory has been proposed as the new explanatory model for these features. However the validity of this model for large scale networks had not been evaluated enough because it needs high computational ability.
In this research theme, simulations for large-scale networks of 2,000 nodes were carried out by a large-scale parallel computer and it is confirmed that complex networks can emerge by this model.
