Abstract: It is known for some time that a random graph G(n, p) con- tains w.h.p. a Hamiltonian cycle if p is larger than the critical value pcrit = (log n+log log n+ωn)/n. The determination of a concrete Hamil- tonian cycle is even for values much larger than pcrit a nontrivial task. In this paper we consider random graphs G(n, p) with p in Ω ̃(1/√n), where Ω ̃ hides poly-logarithmic factors in n. For this range of p we present a distributed algorithm AHC that finds w.h.p. a Hamiltonian cycle in O(log n) rounds. The algorithm works in the synchronous model and uses messages of size O(log n) and O(log n) memory per node.

Abstract: The paper proposes a demand response scheme controlling many domestic electric water heaters (DEWHs) with a price function to consume electric power according to a target schedule. It discusses at length the design of an algorithm to calculate the price function from a target schedule. The price function is used by the control of each DEWH to automatically and optimally minimize its local heating costs. It is demonstrated that the resulting total power consumption approximates the target schedule. The algorithm was successfully validated by simulation with a realistic set of 50 DEWHs assuming perfect knowledge of parameters and water consumption. It is shown that the algorithm is also applicable to clusters of large numbers of DEWHs with statistical knowledge only. However, this leads to a slightly higher deviation from the target schedule.
