摘要:
We consider the problem of minimizing a polynomial on the hypercube [0, 1](n) and derive new error bounds for the hierarchy of semidefinite programming approximations to this problem corresponding to the Positivstellensatz of Schmudgen [Math. Ann., 289 (1991), pp. 203-206]. The main tool we employ is Bernstein approximations of polynomials, which also gives constructive proofs and degree bounds for positivity certificates on the hypercube.
