Title: Min/Max Mean Path Problem Speaker: Zhu Hong Fudan University Date: Friday, November 30, 2007 Time 11:00-12:00PM Venue: Room 3464, HKUST Abstract: Recently, a lot of efforts have been devoted to research on social networks. In this talk, a new model of social networks will be proposed: trustworthy networks. This model asks the maximum trustworthy degree between two agents, which can be reduced to an interesting problem in graph theory: maxmum/minimum mean path problems. We will present some related problems and the hardness result of these problems.
