Abstract

The phase behaviors of two interdependent scale-free (SF) networks under random attack of removing \$1-p\$ fraction of nodes are rich and interesting. Only when the coupling strength \$q=1\$ the percolation phase transition is a first order transition. When \$q\$ is less than 1, at the end stage of the cascade failure, the SF networks will always survive and a non-zero giant cluster \$P\_ınfty\$ will always exist, thus the theoretical critical point \$p\_c\$ goes to \$zero\$. However, a hybrid transition will be observed at the \$1>q>0\$ region, where as \$q\$ descends gradually, the phase transition of \$P\_ınfty\$ will undergoes from quasi-first-order transition, to mix-order transition, then to a quasi-second-order transition, and eventually becomes a real second order transition at \$q=0\$.
