Perhaps you should try some spelling variations:
"post estimation algorithms" » "post optimization algorithms", "post optimisation algorithm", "post approximation algorithms", "pose estimation algorithms", "risk estimation algorithms", "pulses estimation algorithms"
"_ optimized algorithm" » "_ optimized algorithms", "_ optimizer algorithms"
"dose estimation algorithm" » "pose estimation algorithm", "risk estimation algorithm", "cover estimations 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: "((((\"dose estimation algorithm\") OR (\"post estimation algorithms\"))) OR (\"_ optimized algorithm\"))~".
• Removing quotes may allow a broader search: (((( dose estimation algorithm ) OR ( post estimation algorithms ))) OR ( _ optimized algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dose estimation algorithm") OR ("post estimation algorithms"))) OR ("_ optimized algorithm"))*.
