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