For integers k≥ 3 and 1≤ ℓ≤ k− 1, we prove that for any α> 0, there exist ϵ> 0 and C> 0 such that for sufficiently large n∈(k− ℓ) N, the union of a k-uniform hypergraph with minimum vertex degree α n k− 1 and a binomial random k-uniform hypergraph G (k)(n, p) with p≥ n−(k− ℓ)− ϵ for ℓ≥ 2 and p≥ C n−(k− 1) for ℓ= 1 on the same vertex set contains a Hamiltonian ℓ-cycle with high probability. Our result is best possible up to the values of ϵ and C and answers a question of Krivelevich, Kwan and Sudakov.
