Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
policy optimization » topology optimization
same optimization » game optimization, stage optimization, qoe optimization
policy estimation » pose estimation, motion estimation, policy simulation

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: (( same optimization algorithms ) OR ( ((policy estimation) OR (policy optimization)) algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( same optimization algorithms ) or ( ((policy estimation) OR (policy optimization)) algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( same optimization algorithms ) or ( ((policy estimation) OR (policy optimization)) algorithm ))*.
