      abstract     = {We study the performance of quantum annealing for two sets
                      of problems, namely, 2-satisfiability (2-SAT)problems
                      represented by Ising-type Hamiltonians, and nonstoquastic
                      problems which are obtained by addingextra couplings to the
                      2-SAT problem Hamiltonians. In addition, we add to the
                      transverse Ising-type Hamiltonianused for quantum annealing
                      a third term, the trigger Hamiltonian with ferromagnetic or
                      antiferromagneticcouplings, which vanishes at the beginning
                      and end of the annealing process. We also analyze some
                      probleminstances using the energy spectrum, average energy
                      or overlap of the state during the evolution with the
                      instantaneouslow lying eigenstates of the Hamiltonian, and
                      identify some nonadiabatic mechanisms which canenhance the
                      performance of quantum annealing.},
