Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
pose optimization » game optimization, response optimization, policy optimization
pose optimisation » _ optimisation, pose estimation, game optimization
qoe optimization » game optimization, _ optimization, stage optimization

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 ( ((pose optimisation) OR (qoe optimization)) algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( pose optimization algorithms ) OR ( ((pose optimisation) OR (qoe optimization)) algorithm )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( pose optimization algorithms ) or ( ((pose optimisation) OR (qoe optimization)) algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( pose optimization algorithms ) or ( ((pose optimisation) OR (qoe optimization)) algorithm ))*.
