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