This paper has been withdrawn by the author, due to the fact that the main result in it has already been obtained in [1] for any c < e, see also [2] and [3]. Moreover the formula which gives the minimal vertex-cover in a tree (see the abstract) has already been derived in [4]. I thank M. Bauer, O. Golinelli, F. Ricci-Tersenghi, G. Semerjian and M. Weigt for having brought to my attention [1] and M.B. and O.G. for [4]. [1] M. Bauer and O. Golinelli, Eur. Phys. J. B 24, 339-352 (2001); [2] R. M. Karp and M.
