Abstract: The recovery strategy of complex networks is an important topic in the research of network characteristics. However, previous studies only restore nodes unilaterally and ignore the changes of network topology in the process of recovery and failure. In order to break through the sidedness of the previous researches, this paper proposes a multidirectional recovery strategy. This method takes into account the form of network fragmentation (clustering and isolated failure nodes) and reinforces the topology centered on the hub nodes. The method takes fully account of the cascading failure characteristics of the interdependent network. In addition, several synthetic networks are used to verify the effectiveness of the recovery strategy. We discuss the influence of the parameters a,β on the multidirectional recovery strategy and compare it with the strategy of important nodes and common boundary nodes. The experimental results show the multidirectional recovery strategy can effectively improve the robustness of the network at the appropriate cost. These findings provide an effective reference for the recovery strategy of multi-layer network and are of great significance to the recovery of actual networks.
