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

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 adam approximation algorithm ) OR ( modified pose optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified adam approximation algorithm ) or ( modified pose optimisation algorithm ))*.
