Perhaps you should try some spelling variations:
optimized algorithms » optimized algorithm, optimizer algorithms, optimization algorithms
parameter optimized » parameter optimization
game optimization » stage optimization, market optimization, _ optimization
qoe optimization » _ optimization, stage optimization, _ optimisation

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: (( parameter optimized algorithms ) OR ( ((qoe optimization) OR (game optimization)) algorithms ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( parameter optimized algorithms ) or ( ((qoe optimization) OR (game optimization)) algorithms ))~".
• Adding a wildcard symbol may retrieve word variants: (( parameter optimized algorithms ) or ( ((qoe optimization) OR (game optimization)) algorithms ))*.
