Abstract
The goal of this thesis is to examine tight computable bounds on a probability measure generated by its moments. We study measures supported on a real line and propose an extension of the classical moment problem to the so-called rational moments. Specifically, we examine semidefinite and linear optimization formulations for solving the univariate rational Hausdorff moment problem given a vector of moments. We further investigate shifted moments to reduce the distance between probability bounds, and propose a numerical method to better position such shifts. In addition, when only a few raw and shifted moments are known, we derive novel extensions of the Markov and Chebyshev bounds. Motivated by the problem of optimal radiotherapy treatment design, we present a novel and first in its class cutting plane method to be included within the mixed integer branch and cut scheme. Implementing these cuts results in as much as a 40% runtime reduction.
