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

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

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