Abstract :
We propose “Evolutionary System Theory” as a unified approach practically applicable for the real world problems such as real-time adaptive control and mass genetic information analysis. We also propose “Disparity Hypothesis” on the gene replication mechanism of an organism with double stranded DNA that postulates the disparity of fidelity between replication error on leading strand and on lagging strand. Our assertion is that by taking advantages of the disparity an organism could evolve rapidly and acquire robustness even under fluctuating environmental conditions. To investigate how the disparity model works under fluctuating environment, we apply it to two dimensional maximum search problems with multi-peaks and diastrophism, and show that conservative and radical offsprings can be bred together and population can dynamically adapt. In addition, we focus on the mechanism of gene duplication and alternative (selective) splicing so that a system can follow up, adapt to a constantly fluctuating environment, and dynamically expand its own description of specification according to the environment. By introducing the proposed genetic mechanisms into an evolutionary mechanism of machines, we can construct a system which inherits functions from the former generation and develops complexity
