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

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

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