In this paper we consider the weighted k-Hamming and k-Edit distances, that are natural generalizations of the classical Hamming and Edit distances. As main results of this paper we prove that for any k≥ 2 the DECIS-k-Hamming problem is ℙ-SPACE-complete and the DECIS-k-Edit problem is NEXPTIME-complete.
