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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( cover estimations algorithm ) or ( robust ((estimation algorithms) or (optimized algorithm)) ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( cover estimations algorithm ) OR ( robust ((estimation algorithms) OR (optimized algorithm)) )).
• Adding a wildcard symbol may retrieve word variants: (( cover estimations algorithm ) or ( robust ((estimation algorithms) or (optimized algorithm)) ))*.
