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

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