Perhaps you should try some spelling variations:
"_ optimisation algorithm" » "_ optimization algorithms", "_ optimization algorithm"
"_ estimation algorithms" » "_ optimization algorithms", "_ approximation algorithms"
"pose estimation algorithm" » "poses estimation algorithm", "post estimation algorithm", "jose estimation algorithm"

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