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

Try widening your search to All Fields.

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