From the early days of computer science, by the 1940s, researchers

have been interested in tracing parallels and designing computational

models and abstractions of natural phenomena.

Natural Computing

The Grand Challenges*

The GCs aim at defining research questions that tend to be important in the long term, identifying and characterizing potential grand research problems. These may allow the formulation of projects capable of producing major scientific advancements, with practical applications for society and technology. Emphasis is in advancing science, a vision beyond specific projects, a clear and objective success evaluation and a great ambition.*

GC 1: Transforming Natural Computing into a transdisciplinary discipline

How to transpose Natural Computing into a

transdisciplinary context?

17

“Computer science differs from physics in that it is not actually a science. It does not study natural

objects. Neither is it mathematics. It’s like engineering – about getting to do something, rather than dealing with

abstractions”.*“Biology is today an information

science”*** Feynman, R. P. (1996), “The Feynman Lectures on Computation”, In A. J. G. Hey and R. W. Allen (Ed.), (Reading, MA: Addison-Wesley).** Denning, P. J., (2001) (Ed.), The Invisible Future: The Seamless Integration of Technology in Everyday Life, McGraw-Hill.

18

What is the Natural Computing role in this Informational Natural Sciences Era?

Overcoming this challenge will bring two important benefits to Computing and Nature:• A Rethinking (and probably Redesign) of Computing• A New Form of Interacting With and Using Nature

GC 2: Unveiling and harnessing information processing in natural systems

19

Natural systems are open systems that communicate with the environment presenting a complex and emergent

behavior. Complex biological systems must be modeled as self-referential, self-

organizing, and auto-generative systems whose computational behavior goes far

beyond the TM/VN paradigm. The system restructures itself in a hardware-software non-dissociable interaction: the hardware

defines the software, and the software defines the hardware.

20

Are there standards to design natural computing systems?* To what degree defining

standards for the engineering of Natural Computing systems is a limiting factor for the

creative development of the field?

Discussion

Natural Computing: The Past, Present and Future

23

• Focus on:– Designing novel nature-inspired algorithms.– Synthesizing natural phenomena.– Using natural materials for computing.

• Real-world applications are unquestionable, but the field seems to be stuck on the same types of algorithms.

• Researchers are taking efforts to look at and formalize information processing in natural and computational systems.*

The Past and Present

24

• Grand Challenges for the field:– Transforming Natural Computing into a

Transdisciplinary Discipline.– Unveiling and Harnessing Information Processing

in Natural Systems.– Engineering Natural Computing Systems.

And the Future?
