Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
jose optimisation » qoe optimization, _ optimisation
game optimization » stage optimization, qoe optimization, market optimization
same optimization » stage optimization, qoe optimization, market optimization

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((jose optimisation) OR (game optimization)) algorithm ) OR ( same optimization algorithms ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((jose optimisation) OR (game optimization)) algorithm ) or ( same optimization algorithms ))~".
• Adding a wildcard symbol may retrieve word variants: (( ((jose optimisation) OR (game optimization)) algorithm ) or ( same optimization algorithms ))*.
