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