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

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