Research on Topology Optimization of Complex Networks Based-on Rank

In real complex networks, not all nodes were equally important; a method was put forward to measure off rank. We focused on the key nodes, which certain nodes should be protected and a certain connections should be partitioned and reconstructed. Compare with the original structure, the optimized structure was smarter, more tolerant of wrong and resistant of frangibility. The simulation showed that the topology of complex networks was optimized and the work efficiency and resist of frangibility were also improved.
