Researcher devises method to untangle, analyze 'controlled chaos'
A researcher at Indiana University has developed a new mathematical framework to more effectively analyze "controlled chaos," or how interactions among highly complex systems affect their operation and vulnerability.
The new method could potentially be used to improve the resilience of complex critical systems, such as air traffic control networks and power grids, or slow the spread of threats across large networks, such as disease outbreaks.
"By providing reliable results in a rapid manner, these equations allow for the creation of algorithms that optimize the resilience of real interdependent networks," said the study's author, Filippo Radicchi, whose work appears in the journal Nature Physics.
"They may also be helpful in designing complex systems that are more robust, or more easily recoverable," he added.
Radicchi is an assistant professor in the School of Informatics and Computing and a member of the Center for Complex Networks and Systems Research. His equations work by providing a new method to "untangle" multiple complex systems; pulling apart each network, or "graph," for individual analysis; and then reconstructing an overall picture.
