Perhaps you should try some spelling variations:
"_ optimization algorithms" » "_ optimisation algorithm", "_ optimized algorithms", "_ optimizer algorithms"
"_ estimation algorithms" » "_ optimisation algorithm", "_ approximation algorithms"
"jose estimation algorithm" » "pose estimation algorithm", "risk estimation algorithm", "cover estimations algorithm"

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

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