Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
estimations algorithm » estimation algorithm, optimisation algorithm
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
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 ( qoe ((optimization algorithm) or (estimation algorithms)) ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( cover estimations algorithm ) OR ( qoe ((optimization algorithm) OR (estimation algorithms)) )).
• Adding a wildcard symbol may retrieve word variants: (( cover estimations algorithm ) or ( qoe ((optimization algorithm) or (estimation algorithms)) ))*.
