Perhaps you should try some spelling variations:
"_ optimization algorithms" » "_ optimisation algorithm", "_ estimation algorithm", "_ optimizer algorithms"
"pose estimation algorithms" » "pose estimation algorithm", "pose optimisation algorithm", "pose approximation algorithms", "poses estimation algorithms", "post estimation algorithms", "jose estimation algorithms"
"_ optimized algorithms" » "_ optimized algorithm", "_ 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: (("pose estimation algorithms") or ((("_ optimization algorithms") OR ("_ optimized algorithms"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("pose estimation algorithms") OR ((("_ optimization algorithms") OR ("_ optimized algorithms")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"pose estimation algorithms\") or (((\"_ optimization algorithms\") OR (\"_ optimized algorithms\"))))".
• Removing quotes may allow a broader search: (( pose estimation algorithms ) or ((( _ optimization algorithms ) OR ( _ optimized algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("pose estimation algorithms") or ((("_ optimization algorithms") OR ("_ optimized algorithms"))))*.
