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