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

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

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