    "abstract": "We introduce an algorithm aimed to reduce the dimensions of Hilbert space. It\nis used here in order to study the behaviour of low energy states of strongly\ninteracting quantum many-body systems at first order transitions and avoided\ncrossings. The method is tested on different frustrated quantum spin ladders\nwith two legs. The role and importance of symmetries are investigated by using\ndifferent bases of states.",
