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