In this paper, we consider a random geometric graph (RGG) G on n nodes with adjacency distance rn just below the Hamiltonicity threshold and construct Hamiltonian cycles using additional edges called bridges. The bridges by definition do not belong to G and we are interested in estimating the number of bridges and the maximum bridge length, needed for constructing a Hamiltonian cycle. In our main result, we show that with high probability, i.e. with probability converging to one as n → ∞, we…

The first edge in the process that creates a k‐connected graph coincides a.a.s. with the first edge that causes the graph to contain k/2 pairwise edge‐disjoint Hamilton cycles (for even k), or (k−1)/2 Hamilton cycles plus one perfect matching (for odd k), which proves and extends a conjecture of Krivelevich and M ler.

It is shown that if the authors randomly colour the edges of a random geometric graph with sufficiently many colours, then a.a.s. the graph contains a rainbow perfect matching (rainbow Hamilton cycle) if and only if the minimum degree is at least $1$ (respectively, at least €2$).

The proof is constructive and yields a linear time algorithm for finding a Hamiltonian cycle of $\mathcal{G}(n,r)$ asymptotically almost surely, provided r=r(n)ge\sqrt{\frac{\log n}{(\alpha_p -\epsilon)n}}$ for some fixed $\ep silon>0$.
