Complex networks and physics

There is intense research on Complex Network Analysis. Major research work has been undertaken in the last two decades from leading researchers such as Newman, Watts, Barbasi and others. The main impetus is the availability of powerful computers that has made it possible to uncover the complexity of social, behavioural, biological, financial and technological systems. Another new challenge is the use of Sentiment Analysis as social media blogging. This media blogging has become a grave challenge to human society. Fake news, manipulations of news and current public issues for political mileage and arousing hatred among multi-cultural societies has become a serious concern. In this paper, an overview of Complex Network Science research. A review of work is done for the last 20 years. Further, an overview of its research among South-East Asia researchers is presented.
