Perhaps you should try some spelling variations:
"one optimizer algorithms" » "one optimized algorithm", "one optimization algorithms"
"_ optimized algorithms" » "_ optimized algorithm", "_ optimization 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.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("one optimizer algorithms") or ("_ optimized algorithms"))) or ("robust estimation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("one optimizer algorithms") OR ("_ optimized algorithms"))) OR ("robust estimation algorithm")).
• Removing quotes may allow a broader search: (((( one optimizer algorithms ) or ( _ optimized algorithms ))) or ( robust estimation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("one optimizer algorithms") or ("_ optimized algorithms"))) or ("robust estimation algorithm"))*.
