Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
optimized algorithms » optimized algorithm, optimization algorithms
optimizer algorithms » optimized algorithm, optimization algorithms
qoe optimization » game optimization, _ optimization, stage 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: (( qoe optimization algorithm ) or ( game ((optimized algorithms) OR (optimizer algorithms)) ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( qoe optimization algorithm ) OR ( game ((optimized algorithms) OR (optimizer algorithms)) ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( qoe optimization algorithm ) or ( game ((optimized algorithms) OR (optimizer algorithms)) ))*".
