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