Perhaps you should try some spelling variations:
optimization algorithms » estimation algorithms, estimation algorithm, optimized algorithms
optimisation algorithm » estimation algorithm, estimation algorithms
estimations algorithm » estimation algorithm, estimation algorithms
pose estimations » pose estimation, cover estimations, pulses estimation

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

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