Efficient Iterative Methods for Saddle Point Problems
… most preconditioners and iterative methods. A multilevel algorithm is proposed for the solution of such systems, which uses a novel technique for the construction of a basis for the space satisfying the constraints. The proposed algorithm achieves faster convergence on account of implicit …

A multilevel method for meshless solution of the poisson equation in heat transfer and fluid flow
… In this thesis, we present a non-nested multilevel algorithm using the PHS-RBF meshless method for the soluution of the Poisson equation, which commonly arises in numerous heat transfer and fluid flow applications. The PHS-RBF discretization of the Poisson equation leads to a sparse set …

Multilevel Monte Carlo simulation of soft matter using coarse-grained models
… to assess. In this thesis, we investigate a multilevel simulation strategy that leverages one or multiple levels of coarse graining to simulate the exact physical system of interest. This approach is inspired by the multilevel Monte Carlo method, a numerical technique in stochastic simulation …

An investigation of multilevel refinement in routing and location problems
Multilevel refinement is a collaborative hierarchical solution technique. The multilevel technique aims to enhance the solution process of optimisation problems by improving the asymptotic convergence in the quality of solutions produced by its underlying local search heuristics and/or improving …
