Perhaps you should try some spelling variations:
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
optimized algorithms » optimized algorithm, optimization algorithms
optimizer algorithms » optimized algorithm, optimization algorithms
cover estimation » cover estimations, pose estimation, sphere 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 estimation algorithms ) or ( same ((optimized algorithms) or (optimizer algorithms)) ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( cover estimation algorithms ) OR ( same ((optimized algorithms) OR (optimizer algorithms)) ))*.
