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"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"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"))*.
