      abstract     = {The complexity of the GSI/FAIR accelerator facility demands
                      a high level of automation in order to maximize time for
                      physics experiments. Accelerator laboratories world-wide are
                      exploring a large variety of techniques to achieve this,
                      from classical optimization to reinforcement learning. This
                      paper reports on the first results of using Geoff at GSI for
                      automatic optimization of various beam manipulations. Geoff
                      (Generic Optimization Framework $\&$ Frontend) is an
                      open-source framework that harmonizes access to the above
                      automation techniques and simplifies the transition towards
                      and between them. It is maintained as part of the EURO-LABS
                      project in cooperation between CERN and GSI. In dedicated
                      beam experiments, the beam loss of the multi-turn injection
                      into the SIS18 synchrotron has been reduced from $40\%$ to
                      $10\%$ in about 15 minutes, where manual adjustment can take
                      up to 2 hours. Geoff has also been used successfully at the
                      GSI Fragment Separator (FRS) for beam steering. Further
                      experimental activities include closed orbit correction for
                      specific broken-symmetry high-transition-energy SIS18 optics
                      with Bayesian optimization in comparison to traditional
                      SVD-based correction.},
