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