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