Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
optimized algorithms » optimizer algorithms
optimized algorithm » optimizer algorithms
cover optimization » qoe optimization, game 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 optimization algorithms ) or ( robust ((optimized algorithm) or (optimized algorithms)) ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( cover optimization algorithms ) OR ( robust ((optimized algorithm) OR (optimized algorithms)) )).
• Adding a wildcard symbol may retrieve word variants: (( cover optimization algorithms ) or ( robust ((optimized algorithm) or (optimized algorithms)) ))*.
