Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithm, optimized algorithms
estimation algorithms » estimation algorithm, optimisation algorithm, approximation algorithms
market optimization » game optimization, parameter optimization, market capitalization
qoe estimation » pose estimation, _ estimation, cover estimations

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 ( market optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( qoe estimation algorithms ) or ( market optimization algorithms ))*.
