摘要: Random K-out graphs, denoted $\mathbb{H}(n;K)$, are generated by each of the $n$ nodes drawing $K$ out-edges towards distinct selected uniformly at random, and then ignoring orientation arcs. Recently, random graphs have been used in applications as diverse (pairwise) key predistribution ad-hoc networks, anonymous message routing crypto-currency differentially-private federated averaging. In many applications, connectivity graph when some its dishonest, failed, or captured is practical interest. We provide a comprehensive set results on giant component size $\mathbb{H}(n;K_n,\gamma_n)$, i.e., $\gamma_n$ nodes, deleted. First, we derive conditions for $K_n$ that ensure, with high probability (whp), remaining number deleted $\gamma_n=\Omega(n)$ $\gamma_n=o(n)$, respectively. Next, $\mathbb{H}(n;K_n,\gamma_n)$ to component, connected subgraph $\Omega(n)$ whp. This also done different scalings upper bounds provided outside component. Simulation presented validate usefulness finite node regime.
