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

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