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