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