Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
optimized algorithmss » optimized algorithm, optimizer algorithms
optimized algorithms » optimized algorithm, optimizer algorithms, optimization algorithms
qoe optimisation » qoe optimization, _ optimisation, game 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 ((optimized algorithmss) or (optimized algorithms)) ) or ( qoe optimisation algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( qoe ((optimized algorithmss) OR (optimized algorithms)) ) OR ( qoe optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (( qoe ((optimized algorithmss) or (optimized algorithms)) ) or ( qoe optimisation algorithm ))*.
