Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
rough 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.

• Performing a fuzzy search may retrieve terms with similar spellings: (( ((rough approximation) OR (one approximation)) algorithm ) or ( pose optimisation algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((rough approximation) OR (one approximation)) algorithm ) OR ( pose optimisation algorithm )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((rough approximation) OR (one approximation)) algorithm ) or ( pose optimisation algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( ((rough approximation) OR (one approximation)) algorithm ) or ( pose optimisation algorithm ))*.
