Edge-disjoint Hamilton cycles in random graphs
We show that provided log n/n ≤ p ≤ 1 − n−1/4 log n we can with high probability find a collection of bδ(G)/2c edge-disjoint Hamilton cycles in G ∼ Gn,p, plus an additional edge-disjoint matching of size bn/2c if δ(G) is odd. This is clearly optimal and confirms, for the above range of p, a conjecture of Frieze and Krivelevich.
متن کاملRandom Graphs with Few Disjoint Cycles
The classical Erdős-Pósa theorem states that for each positive integer k there is an f(k) such that, in each graph G which does not have k + 1 disjoint cycles, there is a blocker of size at most f(k); that is, a set B of at most f(k) vertices such that G − B has no cycles. We show that, amongst all such graphs on vertex set {1, . . . , n}, all but an exponentially small proportion have a blocke...
متن کاملRandom partitions and edge-disjoint Hamiltonian cycles
Nash-Williams [21] proved that every graph with n vertices and minimum degree n/2 has at least b5n/224c edge-disjoint Hamiltonian cycles. In [20], he raised the question of determining the maximum number of edge-disjoint Hamiltonian cycles, showing an upper bound of b(n+ 4)/8c. Let α(δ, n) = (δ + √ 2δn− n2)/2. Christofides, Kühn, and Osthus [7] proved that for every > 0, every graph G on a suff...
متن کاملRandom graphs containing few disjoint excluded minors
The Erdős-Pósa theorem (1965) states that in each graph G which contains at most k disjoint cycles, there is a ‘blocking’ set B of at most f(k) vertices such that the graph G − B is acyclic. Robertson and Seymour (1986) give an extension concerning any minor-closed class A of graphs, as long as A does not contain all planar graphs: in each graph G which contains at most k disjoint excluded mino...
متن کاملShortest node-disjoint paths on random graphs
A localized method to distribute paths on random graphs is devised, aimed at finding the shortest paths between given source/destination pairs while avoiding path overlaps at nodes. We propose a method based on message-passing techniques to process global information and distribute paths optimally. Statistical properties such as scaling with system size and number of paths, average path-length ...
