For any set N [subset] [0,1] of d distinct collocation nodes, we define the polynomial space
The following result characterizes the polynomial space [Q.
Problems in EXP, NEXP, or EXPSPACE are expected or known to not have polynomial space algorithms, an apparently more stringent condition than not having polynomial time algorithms.
21, we show that the complexity of policy existence problems makes a jump from polynomial time to polynomial space if we consider compressed MDPs instead of flat MDPs.
In the framework of polynomial interpolation, Fekete points are points that maximize the Vandermonde determinant (in any polynomial basis) on a given compact set and thus ensure that the corresponding Lebesgue constant grows (at most) algebraically, being bounded by the dimension of the polynomial space.
j]) is a basis of the total-degree polynomial space,
We shall show, that the polynomial space composed of simple polynomials is not a Haar space.
Observe that this constructive approach immediately yields unisolvence of the interpolation problem, since for any given basis of the underlying polynomial space [V.
First, it comes easy to bound the Lebesgue constant linearly in the dimension of the polynomial space V, which already shows that the Xu points are good candidates for interpolation purposes.
