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