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

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: (( cover estimation algorithms ) OR ( _ optimizer algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( cover estimation algorithms ) or ( _ optimizer algorithms ))*.
