Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
pose approximation » one approximation, time approximation, _ approximation
pose optimization » qoe optimization, game optimization, response optimization
modified pose » modified male, modified passive

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

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