Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
time approximation » one approximation, _ approximation
pose optimization » qoe optimization, game optimization, response optimization
modified pose » modified male, modified passive
modified time » modified bi1, modified male

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

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