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

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