M. Demange et Vt. Paschos, THE APPROXIMABILITY BEHAVIOR OF SOME COMB INATORIAL PROBLEMS WITH RESPECT TO THE APPROXIMABILITY OF A CLASS OF MAXIMUM INDEPENDENT SET PROBLEMS, Comptes rendus de l'Academie des sciences. Serie 1, Mathematique, 321(5), 1995, pp. 645-648
We introduce a class maximum independent set problems and we give some
conditional results that, leaving from positive or negative hypothese
s on the approximability behaviour of this class, provide approximatio
n results for minimum vertex covering problem and a problem of convex
programming including quadratic programming.
