Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
policy estimation » policy optimization, pose estimation, motion estimation
male optimization » game optimization, market optimization, stage optimization

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

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