Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithm, optimizer algorithms
estimation algorithms » estimation algorithm, optimisation algorithm, approximation algorithms
optimized algorithms » optimized algorithm, optimizer algorithms
qoe estimation » pose estimation, _ estimation, cover estimations

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

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