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

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: "(( same ((optimized algorithmss) OR (optimized algorithms)) ) OR ( sphere estimation algorithms ))~".
• Adding a wildcard symbol may retrieve word variants: (( same ((optimized algorithmss) OR (optimized algorithms)) ) OR ( sphere estimation algorithms ))*.
