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

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

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