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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( qoe optimization algorithm ) or ( same ((optimized algorithm) or (optimization algorithms)) ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( qoe optimization algorithm ) OR ( same ((optimized algorithm) OR (optimization algorithms)) )).
• Adding a wildcard symbol may retrieve word variants: (( qoe optimization algorithm ) or ( same ((optimized algorithm) or (optimization algorithms)) ))*.
