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

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((poses approximation) OR (one approximation)) algorithms ) OR ( pose optimisation algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( ((poses approximation) OR (one approximation)) algorithms ) OR ( pose optimisation algorithm ))*.
