Complexity is usually confused with the term complicated. There
are many different elements, individuals and particles in a
complex system that interact with each other. They also
respond to the environments. These elements, individuals and
particles are inter-genius in terms of the information, knowledge
or otherwise. Interaction involves interchanging information and
knowledge. There is no central control or a centralized
processing unit in a complex system. We are surrounded by
complex systems, for example, our brain, the biosystem,
immune system, traffic, the financial system, society, social
media, economy, etc. are all complex systems. It can also be
seen in a different branch of academics such as physics,
mathematics, biology logistics, sociology, etc. Discussions amongst
various intellectuals reveal that different complex system in
different environments has certain things in common. They
need a common methodology or a common language to be
analyzed and described.
