Perhaps you should try some spelling variations:
"robust estimation algorithms" » "robust estimation algorithm", "robust optimization algorithms", "robust optimisation algorithm", "pose estimation algorithms", "risk estimation algorithms"
"one optimized algorithm" » "one optimized algorithms", "one optimizer algorithms"
"_ optimized algorithm" » "_ optimized algorithms", "_ optimizer algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("one optimized algorithm") OR ("_ optimized algorithm"))) or ("robust estimation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("one optimized algorithm") OR ("_ optimized algorithm"))) OR ("robust estimation algorithms"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"one optimized algorithm\") OR (\"_ optimized algorithm\"))) or (\"robust estimation algorithms\"))*".
• Removing quotes may allow a broader search: (((( one optimized algorithm ) OR ( _ optimized algorithm ))) or ( robust estimation algorithms ))*.
