“…A large amount of literature can be found concerning conditions that are sufficient for the existence of some number of disjoint cycles which may satisfy further restrictive conditions. For examples, we refer to publications [6], [9], [10], [12], [15], [16], [18], [20], [21], [23], [24]. The algorithmic problems concerning cycle packings are typically hard ( [5], [11], [20]) and approximation algorithms are described ( [11], [17]).…”
