A sequence of nonnegative integers S=(s1, s2, , sn) is graphical if there is a graph with vertices v1,v2, ,vn such that deg(vi)=si for each i=1, 2, , n. The graphical degree sequence problem is： Given a sequence of nonnegative integers, determine whether it is graphical or not. In this paper, we consider several variations of the graphical degree sequence problem and give efficient algorithms.
