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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( game optimisation algorithm ) or ( ((policy estimation) OR (policy optimization)) algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( game optimisation algorithm ) OR ( ((policy estimation) OR (policy optimization)) algorithm ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( game optimisation algorithm ) or ( ((policy estimation) OR (policy optimization)) algorithm ))*".
