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