Stochastic Adaptation to Environmental Changes Supported by Endocrine System Principles

Adaptation to a changing environment presents a challenging task for today's electronic systems when operating in dynamic, fluctuating environments. This applies in particular to the systems which are to operate in harsh environments with no possibility for human intervention when the change occurs. As a rule, environmental changes are stochastic and so is the effect they may exhibit on a man-made system. On the other hand, evolution has provided living organisms with in-built mechanisms for adapting to environmental changes. In particular, homeostatic processes are example of such inherent adaptive mechanisms found within human body. Out of many complex and interweaved systems involved in homeostatic processes, hormones and endocrine system are prominent for certain properties they exhibit. In the first place, this refers to communication within the system and control of the regulatory processes, both of which are challenging issues within man-made systems. This paper investigates endocrine system principles applied within adaptive processes in a man-made system when adaptation is of stochastic nature. Presented results refer to applications in systems of modular architecture.
