Half a century ago, economic research took a little-noticed yet dramatic departure from the study of concepts most people ...

Knowing only the building blocks of our own biosphere, can we predict how life may exist on other planets? What factors will ...

We show that all algorithms that search for an extremum of a cost function perform exactly the same, when averaged over all possible cost functions. In particular, if algorithm A outperforms algorithm ...

On December 19, the SFI Press published Volume 4 of Foundational Papers in Complexity Science. Following the publication of ...

The Complex World, originally published in Volume 1 of Foundational Papers in Complexity Science, presents an entirely new framing of nature, of the human role in the natural and technological worlds, ...

A significant body of research has investigated why, as city populations grow, so do violent crime, contagious diseases — and ...

Through meetings, schools, community events, and media, we invite curiosity-driven individuals to share our discoveries and support complex systems science. For more than 35 years, a small team of ...

This paper provides a logical framework for complexity economics. Complexity economics builds from the proposition that the economy is not necessarily in equilibrium: economic agents (firms, consumers ...

Half a century ago, economic research took a little-noticed yet dramatic departure from the study of concepts most people might be familiar with from Econ 101. The field shifted from an almost ...

Societies today face daunting challenges: population growth, rapid urbanization, ecological and environmental disturbances, and an unpredictable global marketplace. To address these complex and ...

The SFI Undergraduate Complexity Research (UCR) program is a 10-week residential experience in complexity science research. Students can select from a menu of projects, or develop a project in ...

We develop a unifying approach for complexity measures, based on the principle that complexity requires interactions at different scales of description. Complex systems are more than the sum of their ...
