We consider vertex percolation on pseudo‐random d$$ d $$‐regular graphs. The previous study by the second author established the existence of phase transition from small components to a linear (in nd$$ \frac{n}{d} $$) sized component, at p=1d$$ p=\frac{1}{d} $$. In the supercritical regime, our main result recovers the sharp asymptotic of the size of the largest component, and shows that all other components are typically much smaller. Furthermore, we consider other typical properties of the largest component such as the number of edges, existence of a long cycle and expansion. In the subcritical regime, we strengthen the upper bound on the likely component size.
We consider the performance of the Depth First Search (DFS) algorithm on the random graph G n, 1+ǫ n , ǫ > 0 a small constant. Recently, Enriquez, Faraud and Ménard [2] proved that the stack U of the DFS follows a specific scaling limit, reaching the maximal height of (1 + o ǫ (1)) ǫ 2 n. Here we provide a simple analysis for the typical length of a maximum path discovered by the DFS.
We consider the performance of the Depth First Search (DFS) algorithm on the random graph $G\left(n,\frac{1+\epsilon}{n}\right)$, $\epsilon>0$ a small constant. Recently, Enriquez, Faraud and Ménard proved that the stack $U$ of the DFS follows a specific scaling limit, reaching the maximal height of $\left(1+o_{\epsilon}(1)\right)\epsilon^2n$. Here we provide a simple analysis for the typical length of a maximum path discovered by the DFS.
We consider vertex percolation on pseudo-random d−regular graphs. The previous study by the second author established the existence of phase transition from small components to a linear (in n d ) sized component, at p = 1 d . In the supercritical regime, our main result recovers the sharp asymptotic of the size of the largest component, and shows that all other components are typically much smaller. Furthermore, we consider other typical properties of the largest component such as the number of edges, existence of a long cycle and expansion.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
