Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
optimizer algorithmss » optimized algorithms, optimized algorithm
optimizer algorithms » optimized algorithms, optimized algorithm
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 ((optimizer algorithms) OR (optimizer algorithmss)) ) OR ( qoe optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( game ((optimizer algorithms) or (optimizer algorithmss)) ) or ( qoe optimization algorithms ))*.
