Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
optimizer algorithms » optimized algorithms
optimized algorithm » optimized algorithms
game optimization » stage optimization, qoe optimization, market optimization
cover » covers, over

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 algorithm) or (optimizer algorithms)) ) or ( game optimization algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( cover ((optimized algorithm) OR (optimizer algorithms)) ) OR ( game optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (( cover ((optimized algorithm) or (optimizer algorithms)) ) or ( game optimization algorithms ))*.
