Although an absolute definition of complexity remains elusive, the term is generally used to characterize a phenomenon that emerges from a collection of objects that interact with each other in various ways – a system. A key aspect of complexity is that the emergent behavior arises as a result of the collective nature of the whole system and without direction from a central authority.
A classic example is a flock of birds. The collection of birds move as one body, but no single bird is directing the flight behavior. Furthermore, people, cells, robots, and numerous other ‘things’ can work collectively to create amazing emergent behaviors. Economies, social networks, cancer, contagion spreading – all are complex systems that impact our financial stability, daily interactions, and general health. Complexity underlies some of society’s most pressing issues, and an approach that embraces the non-equilibrium and highly connected nature of a system can lead to solutions that would be otherwise inaccessible.

Boids website from Craig Reynolds includes animations and descriptions on the modelling of complex swarm behavior based on simple rule sets. The boids model has become an oft-cited example of principles of Artificial Life. Flocking is a particularly evocative example of emergence: where complex global behavior can arise from the interaction of simple local rules. In the boids model (and related systems like the multi-agent steering behavior demos) interaction between simple behaviors of individuals produce complex yet organized group behavior.
The Center for Complex Systems and Brain Sciences at Florida Atlantic University was founded in August, 1985 by Dr. Scott Kelso when he assumed the University’s Eminent Scholar Chair in Science. The overarching objective of the Center is to understand the principles and mechanisms underlying complex behavior on all levels, from molecules and cells to whole brain functioning and even brains (people) working together.

Complexity and Management Complexity and Management is a well developed research area at the Business School of the University of Hertfordshire. Since the beginning of this work in 1992, complexity and management researchers have sought to create links between academic work and organisational practice using a complexity perspective in which the inevitable paradoxes and ambiguities of organisational life are not finally resolved but held in creative tension. This perspective draws on analogies from the natural complexity sciences, interpreted in the sphere of human action in terms of American pragmatism, European process sociology and group psychology, to develop new ways of understanding organisations and their management which emphasise self-organisation and emergence in processes of ordinary conversation and everyday politics.
Complexity & Management Centre Blog – Understanding the complex responsive processes of human organizing. We (Doug Griffin, Chris Mowles, Karen Norman, Nick Sarra, and Ralph Stacey) work together as the staff group supervising the reflexive research of leaders, managers and consultants into their own work in organizations on the Doctor of Management program at the Business School of the University of Hertfordshire. We also work in various combinations in other organizations. On this site we hope to explore day to day interactions between people in the work place as a way of enquiring into management practice. Theposts will take a particular interest in power, recognition and communicative interaction and will set out a critical view of contemporary management theory.
Emergence: Complexity & Organization (E:CO) is an international and interdisciplinary conversation about human organizations as complex systems and the implications of complexity science for those organizations.

The Margaret & H.A. Rey Institute for Nonlinear Dynamics in Medicine (ReyLab), is an interdisciplinary research laboratory at Beth Israel Deaconess Medical Center. The laboratory is affiliated with Harvard Medical School and the Harvard-MIT Division of Health Sciences & Technology. Its mission is to provide new understanding of the dynamical aspects of health and disease via multidisciplinary approaches. In particular, our aim is to create an interdisciplinary laboratory without walls. It is led by Plexus Advisor Ary Goldberger, M.D., a cardiologist at Beth Israel Deaconness Medical Center and Havard Medical School, who has devoted his career to seeking to new understandings of the nonlinear mechanisms and patterns of health and disease.

The New England Complex Systems Institute (NECSI) is an independent academic research and educational institution with students, postdoctoral fellows and faculty. In addition to the in-house research team, NECSI has co-faculty, students and affiliates from MIT, Harvard, Brandeis and other universities nationally and internationally. NECSI has been instrumental in the development of complex systems science and its applications. We study how interactions within a system lead to its behavioral patterns, and how the system interacts with its environment.
The Northwestern Institute on Complex Systems (NICO) is a university-wide institute. It is made of distinguished and diverse group of faculty from all areas of the university, including engineering, swarm robotics, business, natural sciences, education, medicine, law, and the social sciences. NICO seeks to develop new connectionsbetween existing research and to create new knowledge at the boundaries of existing disciplines.

The Society for Complexity in Acute Illness (SCAI). Inflammation and organ dysfunction that accompany trauma and sepsis are complex, multi-focal problems. Though exciting laboratory breakthroughs derived from reductionist approaches await translation to the clinic, few therapeutic options are available today. New paradigms are needed to truly impact care for acute illness.We formed SCAI because we believe passionately that complex systems approaches, involving modeling, simulation, systems biology, chaos theory, and network theory can augment the classical, hypothesis-driven approach that has largely failed to stem the tide of critical illness.We are clinicians, bench scientists, and modelers. We work in hospitals, research institutions, and companies.

SabuSense Plexus Associate Lewis Rhodes created Sabusense to help people trying to “connect the dots” within a different “big picture” in order to make sense of what they think they see happening in schools every day. (It works for other organizations, too.) It draws upon the logic of “Sabu,” the Elephant Boy, who had no choice but to deal with “whole elephants,” as he helped the “Blindered” (not Blind) Men around the Elephant take advantage of the connectedness of the “individual parts” for which they usually were held solely accountable. This way-of-thinking then provides the platform for learning from the 12-year journey of a major (140,000 student) US school district that has been transforming how people think about, and judge, the work of teaching and learning we call schooling.
