Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
pose approximation » time approximation, _ approximation, rough approximations
same optimization » game optimization, stage optimization, qoe 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: (( same optimization algorithms ) or ( ((pose approximation) OR (one approximation)) algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( same optimization algorithms ) OR ( ((pose approximation) OR (one approximation)) algorithms ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( same optimization algorithms ) or ( ((pose approximation) OR (one approximation)) algorithms ))*".
