The bandwidth problem is the problem of numbering the vertices of a

given graph $G$ such that the maximum difference between the numbers

of adjacent vertices is minimal. The problem has a long history and

is known to be NP-complete Papadimitriou [Pa76]. Only few special

cases of this problem are known to be efficiently approximable. In

this paper we present the first constant approximation ratio

algorithms on dense instances of this problem.
