      abstract     = {Lattice Quantum Chromodynamics has made tremendous progress
                      over the last decade. New and improved simulation algorithms
                      and lattice actions enable simulations of the theory with
                      unprecedented accuracy. In the first part of this thesis,
                      novel simulation algorithms for dynamical overlap fermions
                      are presented. The generic Hybrid Monte Carlo algorithm is
                      adapted to treat the singularity in the Molecular Dynamics
                      force, to increase the tunneling rate between different
                      topological sectors and to improve the overall volume
                      scaling of the combined algorithm. With this new method,
                      simulations with dynamical overlap fermions can reach
                      smaller lattice spacings, larger volumes, smaller quark
                      masses, and therefore higher precision than had previously
                      been possible. The second part of this thesis is focused on
                      a large scale simulation aiming to compute the light hadron
                      mass spectrum. This simulation is based on a tree-level
                      Symanzik improved gauge and tree-level improved
                      stout-smeared Wilson clover action. The efficiency of the
                      combination of this action and the improved simulation
                      algorithms used allows to completely control all systematic
                      errors. Therefore, this simulation provides a highly
                      accurate ab initio calculation of the masses of the light
                      hadrons, such as the proton, responsible for $95\%$ of the
                      mass of the visible universe, and confirms Lattice QCD in
                      the light hadron sector.},
