Perhaps you should try some spelling variations:
"_ optimisation algorithm" » "_ optimization algorithms", "_ estimation algorithm"
"_ estimation algorithms" » "_ estimation algorithm", "_ optimization algorithms", "_ approximation algorithms"
"pose optimizer algorithms" » "pose optimized algorithms", "pose optimized algorithm", "pose optimization 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: (((("_ optimisation algorithm") OR ("_ estimation algorithms"))) OR ("pose optimizer algorithms"))~.
• Removing quotes may allow a broader search: (((( _ optimisation algorithm ) or ( _ estimation algorithms ))) or ( pose optimizer algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (((("_ optimisation algorithm") or ("_ estimation algorithms"))) or ("pose optimizer algorithms"))*.
