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"
"risk estimation algorithm" » "pose 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: "((\"_ optimized algorithm\") OR (((\"risk estimation algorithms\") OR (\"risk estimation algorithm\"))))~".
• Removing quotes may allow a broader search: (( _ optimized algorithm ) OR ((( risk estimation algorithms ) OR ( risk estimation algorithm ))))~.
• Adding a wildcard symbol may retrieve word variants: (("_ optimized algorithm") OR ((("risk estimation algorithms") OR ("risk estimation algorithm"))))*.
