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

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: (( qoe estimation algorithms ) OR ( game ((optimized algorithms) OR (optimizer algorithms)) ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( qoe estimation algorithms ) or ( game ((optimized algorithms) OR (optimizer algorithms)) ))~".
• Adding a wildcard symbol may retrieve word variants: (( qoe estimation algorithms ) or ( game ((optimized algorithms) OR (optimizer algorithms)) ))*.
