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
sphere estimation » pose estimation
post » most, cost

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