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