      abstract     = {Among other restrictions, vacuum stability is a theoretical
                      constraint for vacuumconfigurations in BSM theories to be
                      allowed or excluded. But due to multidimensionalfield
                      spaces, computing the vacuum stability is a challenging
                      task. This thesis investi-gates vacuum structures in the
                      N2HDM and the cS2HDM and examines the possibilityto take
                      multiple vacuum decay channels into account. It also
                      introduces three differentalgorithms to compute vacuum
                      stability and compares them. One of these algorithmsis the
                      recently developed code NNBounce that has been refined with
                      a hyperparameteroptimization algorithm and is made publicly
                      available.},
