Perhaps you should try some spelling variations:
optimisation algorithms » optimization algorithms, estimation algorithms, estimation algorithm
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
sphere optimisation » sphere estimation
pose optimisation » qoe optimization, _ optimisation, pose estimation

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( sphere optimisation algorithms ) OR ( pose optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( sphere optimisation algorithms ) or ( pose optimisation algorithm ))*.
