Perhaps you should try some spelling variations:
"_ estimation algorithms" » "_ estimation algorithm", "_ optimization algorithms", "_ optimisation algorithm"
"dose optimized algorithms" » "dose optimized algorithm", "dose optimizer algorithms", "dose optimization algorithms", "jose optimized algorithms"
"done optimized algorithms" » "done optimized algorithm", "done optimizer algorithms", "done optimization algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("dose optimized algorithms") OR ("done optimized algorithms"))) or ("_ estimation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("dose optimized algorithms") OR ("done optimized algorithms"))) OR ("_ estimation algorithms")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"dose optimized algorithms\") OR (\"done optimized algorithms\"))) or (\"_ estimation algorithms\"))".
• Removing quotes may allow a broader search: (((( dose optimized algorithms ) OR ( done optimized algorithms ))) or ( _ estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("dose optimized algorithms") OR ("done optimized algorithms"))) or ("_ estimation algorithms"))*.
