Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm
estimation algorithms » estimation algorithm, optimization algorithms, approximation algorithms
optimize algorithms » optimized algorithms, optimizer algorithms, optimized algorithm
_ optimize » _ optimized, _ optimise

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 (estimation algorithms)) ) or ( _ optimize algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( qoe ((optimisation algorithm) OR (estimation algorithms)) ) OR ( _ optimize algorithms )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( qoe ((optimisation algorithm) OR (estimation algorithms)) ) or ( _ optimize algorithms ))".
• Adding a wildcard symbol may retrieve word variants: (( qoe ((optimisation algorithm) OR (estimation algorithms)) ) or ( _ optimize algorithms ))*.
