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

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

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