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