Cloud Model-Based Artificial Immune Network for Complex Optimization Problem

الملخص EN

This paper proposes an artificial immune network based on cloud model (AINet-CM) for complex function optimization problems.

Three key immune operators—cloning, mutation, and suppression—are redesigned with the help of the cloud model.

To be specific, an increasing half cloud-based cloning operator is used to adjust the dynamic clone multipliers of antibodies, an asymmetrical cloud-based mutation operator is used to control the adaptive evolution of antibodies, and a normal similarity cloud-based suppressor is used to keep the diversity of the antibody population.

To quicken the searching convergence, a dynamic searching step length strategy is adopted.

For comparative study, a series of numerical simulations are arranged between AINet-CM and the other three artificial immune systems, that is, opt-aiNet, IA-AIS, and AAIS-2S.

Furthermore, two industrial applications—finite impulse response (FIR) filter design and proportional-integral-differential (PID) controller tuning—are investigated and the results demonstrate the potential searching capability and practical value of the proposed AINet-CM algorithm.
