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

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( cover estimation algorithms ) OR ( _ ((optimizer algorithms) OR (optimized algorithm)) ))~".
• Adding a wildcard symbol may retrieve word variants: (( cover estimation algorithms ) OR ( _ ((optimizer algorithms) OR (optimized algorithm)) ))*.
