We study the Min--SCCP on a partition of a complete weighted digraph into vertex-disjoint cycles of minimum total weight. This problem is a generalization of the known traveling salesman problem (TSP) and a special case of the classical vehicle routing problem (VRP). It is known that the problem Min--SCCP is strongly -hard and preserves its intractability even in the geometric statement. For the Euclidean Min--SCCP in with , we construct a polynomial-time approximation scheme, which generalizes the approach proposed earlier for the planar Min-2-SCCP. For any fixed the scheme finds a -approximate solution in time.
