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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( qoe ((optimized algorithms) or (optimisation algorithm)) ) or ( sphere estimation algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( qoe ((optimized algorithms) OR (optimisation algorithm)) ) OR ( sphere estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (( qoe ((optimized algorithms) or (optimisation algorithm)) ) or ( sphere estimation algorithms ))*.
