Perhaps you should try some spelling variations:
"post estimation algorithms" » "post optimization algorithms", "post optimisation algorithm", "post approximation algorithms", "risk estimation algorithms", "pulses estimation algorithms"
"_ optimized algorithm" » "_ optimized algorithms", "_ optimizer algorithms"
"pose estimation algorithm" » "poses estimation algorithm", "jose estimation algorithm", "dose estimation algorithm"

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