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"
"post estimation algorithm" » "pose estimation algorithm", "risk estimation algorithm", "pulses estimation algorithm"

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

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