Perhaps you should try some spelling variations:
variational segmentation » variational formulation, variational iteration
formation segmentation » estimation segmentation, motion segmentation, formation implementation
method decision » methods decision, method precision, method design
decision get » decisions get, decision agent, decision gate
libri » libro, libr, libre

• The words AND, OR and NOT may confuse the search; try adding quotes: "((formation segmentation) OR (variational segmentation)) method decision get libri".
• Adding a wildcard symbol may retrieve word variants: ((formation segmentation) OR (variational segmentation)) method decision get libri*.
