Abstract
In this paper the problem of finding an affine lower bound function for a multivariate polynomial is considered. For this task, a number of methods are presented, all based on the expansion of the given polynomial into Bernstein polynomials. Error bounds and numerical results for a series of randomly-generated polynomials are given.
