Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm
estimation algorithms » estimation algorithm, optimization algorithms, approximation algorithms
optimized algorithm » optimized algorithms, 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: (( qoe ((optimisation algorithm) OR (optimized algorithm)) ) OR ( qoe estimation algorithms ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( qoe ((optimisation algorithm) OR (optimized algorithm)) ) OR ( qoe estimation algorithms ))".
• Adding a wildcard symbol may retrieve word variants: (( qoe ((optimisation algorithm) OR (optimized algorithm)) ) OR ( qoe estimation algorithms ))*.
