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

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

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