Taming Complexity: Controlling Squishy Networks
Center of Complex Networks Research, Northeastern University
Division of Network Medicine, Harvard University
The ultimate proof of our understanding of biological or technological systems
is reflected in our ability to control them. While control theory offers
mathematical tools to steer engineered and natural systems towards a desired
state, we lack a framework to control complex self-organized systems.
Here we explore the controllability of an arbitrary complex network, identifying
the set of driver nodes whose time-dependent control can guide the systems
entire dynamics. We apply these tools to several real networks, unveiling how
the network topology determines its controllability. Virtually all technological
and biological networks must be able to control their internal processes. Given
that, issues related to control deeply shape the topology and the vulnerability
of real systems. Consequently, unveiling the control principles of real
networks, the goal of our research, forces us to address series of fundamental
questions pertaining to our understanding of complex systems.
Finally, I will illustrate the power of network-based tools by applying it to
the connectome of C elegans, identifying new neurons involved in locomotion, and
offering direct experimental evidence for the validity of these
