Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
pose optimisation » qoe optimization, _ optimisation, pose estimation
game optimization » stage optimization, qoe optimization, market optimization
risk optimization » robust optimization, _ optimization, qoe 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 (game optimization)) algorithm ) or ( risk optimization algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((pose optimisation) OR (game optimization)) algorithm ) OR ( risk optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (( ((pose optimisation) or (game optimization)) algorithm ) or ( risk optimization algorithms ))*.
