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

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"qoe ((optimized algorithms) OR (optimizer algorithms))\\") or (\\"qoe estimation algorithms\\"))\"".
• Removing quotes may allow a broader search: (( qoe ((optimized algorithms) OR (optimizer algorithms)) ) or ( qoe estimation algorithms )).
