Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm
estimation algorithms » estimation algorithm, optimization algorithms, approximation algorithms
optimized algorithm » optimized algorithms, optimizer 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: (( poses ((optimisation algorithm) or (optimized algorithm)) ) or ( game estimation algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( poses ((optimisation algorithm) OR (optimized algorithm)) ) OR ( game estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (( poses ((optimisation algorithm) or (optimized algorithm)) ) or ( game estimation algorithms ))*.
