Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
optimization algorithm » optimisation algorithm, estimation algorithm, estimation algorithms
optimized algorithms » optimized algorithm, optimizer algorithms
risk optimized » write optimized

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

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