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