this paper examines the specific role played by a key component of OSNs: the extremely popular and widespread set of third-party applications on some of the most popular OSNs. With over 81,000 third-party applications on Facebook alone, their impact is hard to predict and even harder to study.

使用Matlab来实现旅行商问题的一些代码，希望对用Matlab学习优化问题的人有些帮助(tere is some code about TSP problem which is written by matlab,i hope it is helpful to some people who is learning matlab.)
