In this paper, we consider the problem for which lengths an MDS Euclidean self-dual code over {F}_{q} exists. This problem is completely solved for the case where q is even. For q is odd, some q-ary MDS Euclidean self-dual codes were obtained in the literature. In the present paper, we construct new classes of q-ary MDS Euclidean self-dual codes by using generalized Reed-Solomon (GRS for short) codes and extended GRS codes. Finally, we talk some recent progress and future research problems on this topic.
