From: Non-Markovian recovery makes complex networks more resilient against large-scale failures
An active (A-type) node may fail spontaneously at the rate β1 to become an X-type node due to internal causes, or it may fail at the rate β2 to become a Y-type node when the number of its A-type neighbors n is less than or equal to a threshold m setting the necessary neighboring support for the proper functioning of a node. In the NMR model, the X-type and Y-type nodes take the time duration τ1 and τ2 from the time they are generated to recover, respectively. In the MR model, the X-type and Y-type nodes recover, respectively at the rates μ1 and μ2.
