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

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

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