Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, estimation algorithm, estimation algorithms
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
estimation algorithmss » estimation algorithms, estimation algorithm, optimization algorithms
game estimation » pose estimation, game optimization

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( qoe ((optimization algorithm) OR (optimisation algorithm)) ) or ( game estimation algorithmss ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( qoe ((optimization algorithm) OR (optimisation algorithm)) ) OR ( game estimation algorithmss )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( qoe ((optimization algorithm) OR (optimisation algorithm)) ) or ( game estimation algorithmss ))".
• Adding a wildcard symbol may retrieve word variants: (( qoe ((optimization algorithm) OR (optimisation algorithm)) ) or ( game estimation algorithmss ))*.
