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

Try widening your search to All Fields.

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