Based on the HeXie management theory in economic management, a novel immune optimization information
network model, named HeXie evolutionary information network(HEIN), is proposed. The model considers the settling of the optimization problem as the process of energy’s maximization in information network. It contains two rule sets that are He set and Xie set to control and manage the evolving process which is more elaborate and effective than the one that simulates the organisms or nature evolution simply. Experimental results show that HEIN can maintain the solution’s diversity better with a high convergence rate, and is also an effective and robust technique for optimization.
