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

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (( qoe estimation algorithms ) or ( _ ((optimize algorithms) or (optimizer algorithms)) ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( qoe estimation algorithms ) OR ( _ ((optimize algorithms) OR (optimizer algorithms)) )).
• Adding a wildcard symbol may retrieve word variants: (( qoe estimation algorithms ) or ( _ ((optimize algorithms) or (optimizer algorithms)) ))*.
