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"
"_ optimized algorithms" » "_ optimized algorithm", "_ optimizer algorithms", "_ optimization algorithms"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"pose optimisation algorithm\") OR (\"_ estimation algorithms\"))) OR (\"_ optimized algorithms\"))~".
• Removing quotes may allow a broader search: (((( pose optimisation algorithm ) OR ( _ estimation algorithms ))) OR ( _ optimized algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (((("pose optimisation algorithm") OR ("_ estimation algorithms"))) OR ("_ optimized algorithms"))*.
