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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( cover ((optimized algorithm) OR (optimized algorithms)) ) or ( qoe optimization algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( cover ((optimized algorithm) OR (optimized algorithms)) ) OR ( qoe optimization algorithm ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( cover ((optimized algorithm) OR (optimized algorithms)) ) or ( qoe optimization algorithm ))*".
