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