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