Simple regression analysis using Python
This article introduces simple regression analysis illustrated with a simple example and shows how to calculate it using Python.
Calculate connected dominating sets (CDS)
It is believed that the minimum connected dominating set problem cannot be solved in polynomial time. To the best of my knowledge, there is no source code available for approximation algorithms. Therefore, I decide to implement one proposed by M. Rai in 2009.
Calculate minimum dominating sets
This blog takes notes of dominating sets and shows how to calculate its value with the Python package, NetworkX.

泊松分布和幂律分布对应于均匀网络和非均匀网络
前天看一篇关于社交网络的论文，讨论到均匀和非均匀网络，进一步了解到其背后的理论基础是数学的泊松分布和幂律分布。碰巧了解到幂律分布也是长尾理论的数学基础，而长尾理论不仅对帕雷托法则(Pareto principle)进行补充，而且很好诠释了web 2.0时代的商业模式，简单是太美了。本文首先介绍帕雷托法则和长尾理论，接着讨论其背后的数学基础：泊松分布、幂律分布，最后，介绍该数学基础引申出来的均匀与非均匀网络。
