Perhaps you should try some spelling variations:
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
optimized algorithms » optimizer algorithms, optimization algorithms
optimized algorithm » optimizer algorithms
policy estimation » policy optimization, pose estimation, motion estimation
same » some

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

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