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

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: (("_ optimized algorithm") OR ((("qoe optimisation algorithm") OR ("qoe estimation algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"_ optimized algorithm\") or (((\"qoe optimisation algorithm\") OR (\"qoe estimation algorithms\"))))~".
• Removing quotes may allow a broader search: (( _ optimized algorithm ) or ((( qoe optimisation algorithm ) OR ( qoe estimation algorithms ))))~.
• Adding a wildcard symbol may retrieve word variants: (("_ optimized algorithm") or ((("qoe optimisation algorithm") OR ("qoe estimation algorithms"))))*.
