Perhaps you should try some spelling variations:
"_ optimization algorithm" » "_ optimization algorithms", "_ optimisation algorithm", "_ optimized algorithm"
"_ estimation algorithms" » "_ optimization algorithms", "_ optimisation algorithm", "_ approximation algorithms"
"poses estimation algorithm" » "pose estimation algorithm", "pulses estimation algorithm", "cover estimations algorithm"

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

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