Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
policy optimization » topology 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 optimisation) OR (qoe optimization)) algorithm ) or ( policy optimization algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((pose optimisation) OR (qoe optimization)) algorithm ) OR ( policy optimization algorithm ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((pose optimisation) OR (qoe optimization)) algorithm ) or ( policy optimization algorithm ))*".
