A new evaluation method of network survival fitness(NSF)based on multi-objective optimization is proposed to measure the adaptability of network topology against failure and attacks in networks. NSF is evaluated by considering network efficiency
network robustness and network cost
and overcomes the shortcoming of single-objective optimization method. The results show that the Hub formation balances the need for efficiency and robustness quite well
and that network survival fitness can be enhanced by improving the topological homogeneous degree distribution. It is also found that the proposed method effectively evaluates the survival fitness of different network structures under dynamic environments
and provides useful guidance in designing
optimizing and reconfiguring of the network topology.
