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

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( some ((optimizer algorithmss) OR (optimizer algorithms)) ) OR ( sphere estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( some ((optimizer algorithmss) or (optimizer algorithms)) ) or ( sphere estimation algorithms ))*.
