Perhaps you should try some spelling variations:
"_ estimation algorithms" » "_ optimization algorithms", "_ optimisation algorithm", "_ approximation algorithms"
"jose estimation algorithm" » "pose estimation algorithm", "cover estimations algorithm", "pulses estimation algorithm"
"risk estimation algorithm" » "pose 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: (((("jose estimation algorithm") OR ("risk estimation algorithm"))) or ("_ estimation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("jose estimation algorithm") OR ("risk estimation algorithm"))) OR ("_ estimation algorithms")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"jose estimation algorithm\") OR (\"risk estimation algorithm\"))) or (\"_ estimation algorithms\"))".
• Removing quotes may allow a broader search: (((( jose estimation algorithm ) OR ( risk estimation algorithm ))) or ( _ estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("jose estimation algorithm") OR ("risk estimation algorithm"))) or ("_ estimation algorithms"))*.
