Perhaps you should try some spelling variations:
"pose estimation algorithms" » "pose estimation algorithm", "pose optimization algorithms", "pose optimisation algorithm", "poses estimation algorithms", "post estimation algorithms", "jose estimation algorithms"
"_ optimized algorithms" » "_ optimized algorithm", "_ optimization algorithms"
"_ optimizer algorithms" » "_ optimized algorithm", "_ optimization algorithms", "_ optimize algorithms", "_ optimise algorithms"

Try widening your search to All Fields.

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