This algorithm can distinguish the critical nodes of the network with high precision, and the accuracy can reach 90%. The accuracy of this algorithm can reach 100% when identifying non-critical nodes <ref>Zhang, Y.; Zhang, Z.; Zhang, B.

The LASCNN algorithm establishes k hop neighbor list and a duplicate free pair wise connection list based on k hop information. If the neighbors are stay connected then the node is non critical
