"Going back to our roots": second generation biocomputing
Researchers in the field of biocomputing have, for many years, successfully
"harvested and exploited" the natural world for inspiration in developing
systems that are robust, adaptable and capable of generating novel and even
"creative" solutions to human-defined problems. However, in this position paper
we argue that the time has now come for a reassessment of how we exploit
biology to generate new computational systems. Previous solutions (the "first
generation" of biocomputing techniques), whilst reasonably effective, are crude
analogues of actual biological systems. We believe that a new, inherently
inter-disciplinary approach is needed for the development of the emerging
"second generation" of bio-inspired methods. This new modus operandi will
require much closer interaction between the engineering and life sciences
communities, as well as a bidirectional flow of concepts, applications and
expertise. We support our argument by examining, in this new light, three
existing areas of biocomputing (genetic programming, artificial immune systems
and evolvable hardware), as well as an emerging area (natural genetic
engineering) which may provide useful pointers as to the way forward.Comment: Submitted to the International Journal of Unconventional Computin
A Review on the Application of Natural Computing in Environmental Informatics
Natural computing offers new opportunities to understand, model and analyze
the complexity of the physical and human-created environment. This paper
examines the application of natural computing in environmental informatics, by
investigating related work in this research field. Various nature-inspired
techniques are presented, which have been employed to solve different relevant
problems. Advantages and disadvantages of these techniques are discussed,
together with analysis of how natural computing is generally used in
environmental research.Comment: Proc. of EnviroInfo 201
Evolution and development of complex computational systems using the paradigm of metabolic computing in Epigenetic Tracking
Epigenetic Tracking (ET) is an Artificial Embryology system which allows for
the evolution and development of large complex structures built from artificial
cells. In terms of the number of cells, the complexity of the bodies generated
with ET is comparable with the complexity of biological organisms. We have
previously used ET to simulate the growth of multicellular bodies with
arbitrary 3-dimensional shapes which perform computation using the paradigm of
"metabolic computing". In this paper we investigate the memory capacity of such
computational structures and analyse the trade-off between shape and
computation. We now plan to build on these foundations to create a
biologically-inspired model in which the encoding of the phenotype is efficient
(in terms of the compactness of the genome) and evolvable in tasks involving
non-trivial computation, robust to damage and capable of self-maintenance and
self-repair.Comment: In Proceedings Wivace 2013, arXiv:1309.712
