Perhaps you should try some spelling variations:
"pose optimisation algorithm" » "pose optimization algorithms", "pose estimation algorithm", "qoe optimization algorithm", "_ optimisation algorithm"
"_ estimation algorithms" » "_ estimation algorithm", "_ optimization algorithms", "_ approximation algorithms"
"_ optimise algorithms" » "_ optimized algorithms", "_ optimizer algorithms", "_ optimized algorithm", "_ optimize algorithms"

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: (((("pose optimisation algorithm") OR ("_ estimation algorithms"))) OR ("_ optimise algorithms"))~.
• Removing quotes may allow a broader search: (((( pose optimisation algorithm ) or ( _ estimation algorithms ))) or ( _ optimise algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (((("pose optimisation algorithm") or ("_ estimation algorithms"))) or ("_ optimise algorithms"))*.
