Abstract
We study functions having norm less than a given constant , and agreeing with a given function on a finite set . Let denote the convex set formed by taking the -jets of all such at a given finite set . We provide an efficient algorithm to compute a convex polyhedron , such that $$ \Gamma_f (S,cM) \subset \tilde{\Gamma}_f (S,M) \subset \Gamma_f (S,CM), cCmn$.
