Perhaps you should try some spelling variations:
"_ optimisation algorithm" » "_ optimization algorithms", "_ estimation algorithms", "_ optimization algorithm"
"_ optimized algorithm" » "_ optimized algorithms", "_ optimizer 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: (("robust estimation algorithm") or ((("_ optimisation algorithm") or ("_ optimized algorithm"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("robust estimation algorithm") OR ((("_ optimisation algorithm") OR ("_ optimized algorithm")))).
• Removing quotes may allow a broader search: (( robust estimation algorithm ) or ((( _ optimisation algorithm ) or ( _ optimized algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("robust estimation algorithm") or ((("_ optimisation algorithm") or ("_ optimized algorithm"))))*.
