Perhaps you should try some spelling variations:
optimisation » optimization, optimizacion, utilisation
optimezation » optimization, optimizacion, optimizaron
atomisation » atomizacion
atomization » atomizacion, automatization, customization
factorization » autorizacion, sectorizacion
same* » some*

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((optimisation OR optimezation) or (atomisation or atomization)) or factorization) of same~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((optimisation OR optimezation) OR (atomisation OR atomization)) OR factorization) of same*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((optimisation OR optimezation) or (atomisation or atomization)) or factorization) of same*".
