Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
approximation algorithm » approximation algorithms
pose optimization » qoe optimization, game optimization, response optimization
one approximation » time approximation, _ approximation, rough approximations

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

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