The intersection and interpenetrate of life science and engineering science are the conspicuous character of recent development of science and tenology. Envoluation, as an important self-adapt method drawn from life phenomena, has been generally recongnized and widely applied to problem solving. But the current evolving models have a common deficiency: they can not well reflect that the evoluation of the system is in fact the co-evolution under numerous local reciprocity.
