The complex behavior of systems in nature is rooted in intricate mechanisms of interaction that often supersede human-made systems in terms of reliability, power efficiency, and computational capacity. Researchers have begun to realize that natural systems are a great source of inspiration for novel algorithms in computation and communication systems. The International Workshop on Natural Computing (IWNC) is a platform that brings together computer scientists, biologists, mathematicians, electronic engineers, physicists, and social scientists to critically assess present findings in the...
