Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm
estimation algorithms » estimation algorithm, optimization algorithms, approximation algorithms
policy optimisation » policy optimization, topology optimization
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 pose estimation algorithms ) OR ( modified policy optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified pose estimation algorithms ) or ( modified policy optimisation algorithm ))*.
