Perhaps you should try some spelling variations:
optimized algorithms » optimized algorithm, optimizer algorithms, optimization algorithms
parameter optimized » parameter optimization
one optimisation » _ optimisation, game optimization, _ optimization
qoe optimization » game optimization, _ optimization, stage 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: (( ((one optimisation) OR (qoe optimization)) algorithm ) OR ( parameter optimized algorithms ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((one optimisation) OR (qoe optimization)) algorithm ) or ( parameter optimized algorithms ))~".
• Adding a wildcard symbol may retrieve word variants: (( ((one optimisation) OR (qoe optimization)) algorithm ) or ( parameter optimized algorithms ))*.
