Abstract

Collective computations take place in nature in two major classes of architecture, which we can roughly classify as "solid" (the standard, synaptic connectivity picture) versus those that are performed by "liquid" networks, such as the Immune system or ant colonies. Additionally, other solutions (or constraints) associated with plant and fungal communication, or the potential of unicellular systems such as Physarum emerged as relevant actors. Finally, synthetic systems such as robot swarms and engineered communicating cells offer additional avenues for inquiry.There are many questions that we need to address, in particular: What are the computational limits associated with the physical state displayed by the collective? Are there a limited number of possibilities (as those already observed) or many others? What can or cannot be computed? How do we define a proper evolutionary framework to understand the origins of different solutions? What are the trade-offs involved here? Can we evolve other solutions using artificial life models? Can a statistical physics approach to computa8on including physical phases help finding universality classes? What is the impact of fluid versus solid on the values and meaning of integrated information theory? Answering these questions will help to define a theoretical framework for the emergence and design of cognitive networks.

ICREA research professor at Pompeu Fabra University (UPF), head of the Complex Systems Laboratory of the Institute of Evolutionary Biology (IBE), external professor of Santa Fe Institute (New Mexico, USA) and ECLT fellow. His academic training combines biology and physics, the discipline in which he did his PhD, and he has focused his career as a researcher on complex systems: from the evolutionary dynamics of viruses and synthetic biology to the great evolutionary transitions, the emergence of cognition and the terraformation of ecosystems. His work has been awarded with James McDonnell and ERC Advanced Grants.
