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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("_ optimisation algorithm") or ("one optimized algorithm"))) or ("pose estimation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("_ optimisation algorithm") OR ("one optimized algorithm"))) OR ("pose estimation algorithms")).
• Removing quotes may allow a broader search: (((( _ optimisation algorithm ) or ( one optimized algorithm ))) or ( pose estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("_ optimisation algorithm") or ("one optimized algorithm"))) or ("pose estimation algorithms"))*.
