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

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

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