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

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

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